I started this thread because I wrote up the following giant post and figured it has everything to do with the story, yet adds nothing to it other then my rambling on about character and story development.  So instead of posting there, I'm posting here and offering my help to those interested in writing to pick my brain as well as others to help you accomplish your goals.
 
The statement made that prompted it was that I shouldn't give out too much information because some readers like to be surprised.
I posted an off topic comment regarding what I had planned for my characters which prompted that statement.
While in most cases that is absolutely true, in this case, nearly all, if not all of the readers are also co-authors.  Team writing is difficult to do because while you want to surprise the others with your writing, you also have to make sure they know where you're going with your story.  The balance is a tough one to maintain and since the only input we ever get is from other lore writers, it's tough to remember that they're also the readers and need to be entertained as well.  It started off small but mutated into this overly long rambling answer.
 
      Don't give out too much  history or future?
      Either way it doesn't matter.  The  past can't be changed and  no matter what happens, the final chapter has  already been wrote for my characters and is  what I'm always working to get to no matter  what anyone else thinks  they're going to do.  It will happen at some  point, it's just a matter  of how long it takes to get there.  So if  everyone knows that's what I  have planned, then they're not going to go  out and try to assassinate  any of my lead characters and succeed and  really screw me out of my  whole story.  That'd get me to quit on the spot  for sure.  But since no  one here is that desperate to be rid of me,  then there's no problem  with people knowing it.  In fact it's probably  beneficial that other  writers know it.  Sure as a reader you might be  upset, but as an  author, you can appreciate the value in knowing my  goals and where I  plan on taking my story.  You have clear direction by  knowing my  direction.
      Every good story has an ending.  The difference between   writers is some of us know the ending before the story ever begins   begins, and others don't and just write until they feel they've reach a   conclusion or the conclusion.  I prefer to know my ending and I'm not   going to let anyone get in the way of it.  Details and events that   happen between then and now, I go with on the fly without any problems, I   roll with the punches, but I always have direction because I know  where  I'm going to end up.  I've mentioned a few times to multiple  people, I  will never let my main characters be captured or killed in  this RP.  I  will not let anyone put them into an impossible situation.   I will not  ever let anyone mutate them or genetically alter them or  mess them up.   Why?  Well, that's why.  I know how it ends for each of  them already,  and they have their paths they must follow.  Don't get me  wrong, I'm not  talking about scars, tattoos, piercings, etc...  I'm  talking bodily  mutilation and changes that can never be undone.
      Casey for  example, I've been careful to describe her as  looking like a normal  human because even though she was born an Advent,  she's never refined  her Advent abilities and gained their looks.  The  white eyes and body  markings for example.  It's extremely important to  her story that she  remains looking like a normal human.  I will not  allow anyone to teach  her how to refine her powers because then she  would have to take on the  established looks and I will not let that  happen.  As I've told Alpha I  believe it was, Casey's unrefined  abilities also gives me a story option  in an extreme crisis.  She can  become very emotional and tap into it  and unleash a whole world of  hurt, but it would be unrealistic for her  to be able to do it all of  the time, and after she does it the first  time, it would scare her to  death about those abilities, and further  cement her drive to stay away  from the Advent 'faith' and give her  unimaginable understanding about  the fears that normal humans have of  her people.
      Now I know people who read stories, some read the final   chapter first others refuse to even read the back cover until they've   completed every single page between them.  If someone reading is one of   those that hates to know the ending, well too bad.  Consider what I've   already said about the future as foreshadowing.  Granted it's not in   story, but with how crazy out there some people are getting with their   powers / special abilities / artifacts / super artifacts / unheard of   before ships, I wouldn't be surprised if someone gains the ability to   see into the future and spills it all anyway...  To me personally, those   are roads I'm not going to walk.  My story is based on the game and   though I take liberties with certain aspects of it, those liberties are   all grounded on game content.  The gas giants platforms is one of those   liberties.  Sure there are several dozen ways it can happen.  I hope   that others explore them, however, since in the lore I'm the first one   to really get around to talking about the colonization of a gas giant, I   figure I should detail the process a bit.  Later on I will just refer   to it as colonizing it, just as I expect others to simply say they   colonized it, however, the act of colonizing is a piece of story we can   all take liberties on and describe it in our own ways.  I have the   opportunity to describe the process and I wanted to jump on it.  I'd be   very interested in seeing someone else's take on how it happens.  But   until that time comes, I'm going to run wild and let my imagination do   it's job unchecked for once.  If anyone has some ideas they want to   share, then by all means, let me know and I'll do my best to include them.    I'm going to have fun with it.
      Also, once I start telling stories about my character's   past...  Their futures will become known.  I've avoided doing it because   I've never really wanted to rewrite any of my old stuff that was done   long before entrenchment was ever released, but all this waiting around   for Kyrene to finish has put me in the mood to go back and tell those   stories.  And it's not like I can just post those stories either,   because Entrenchment and Diplomacy changed things.  So most of them do   need to be rewrote.  Like Todd's history for example.
      Before  entrenchment, I just had him being a ship's engineer  and moving over  into research because he was never given his command, a  move which  ultimately made him unhappy enough to quit the service and  give up until  he was hired by Henry.  Post diplomacy, I was  legitimately given the  angle I originally wanted for him, and had him  being reassigned into  R&D to get him out of the field and using his  talents working on a  new ship design and improvements and having  access to all of the latest  and greatest the TEC has to offer, which  combined with his natural  gifted engineering capabilities makes him an  attractive person to go  after for a fledgling business, who eventually  offers him enough to  steal him away.  Now I portray him as a more happy  go lucky guy who knew  how bad things were going to get for him rather  then a guy who hit rock  bottom and is just relieved to be doing  something different.  His  reputation is established a I originally  intended it, rather then having  to build up to it as a member of the  RFT.  An added bonus would have  been to have him retain his rank.  I've  never really been interested in  re merging onto the fold of the TEC,  however, that being said, for any  other characters out there,  especially like Tim in my group, he kept his  rank.  That is a bonus.   I'm not sure if I will ever use it, but with  the dynamics of group  story telling, any bonus you get to hang onto is  exactly that.  A  bonus.
      Details in my characters history have changed because of  the  two micro expansions, and more changed because of Distant Stars, but   even so, the story remains the same because like I said, I already have   the ending wrote.  I have the beginning and I have the ending.  The   journey between the two points can be as fluid as the the ocean, but I   have my two end points.  Good imagery would be this: Stretch a rubber   band between two fingers in one hand and use the other to move the mid   point all around.  That's how I tell my stories.  The middle can be   anywhere the rubber band can stretch to, but it's always attached to the   two end points, and as long as I don't try to pull or get pulled too   far in any one direction, the rubber band doesn't break, and I'm keeping   to my vision.
      So in Todd's case, the whole taking over of  the company is a  detail that will be made known by telling that part of  his history.   Roesh vowing revenge and being willing to die to achieve  it, is  something that will be known by telling the middle of his current   life's history when the Vasari first invade.  Henry returning to his   family is a detail that will be known once his early life's story has   been told even before the first invasion. 
      Casey's  unwavering loyalty, remaining with the company and  staying by Todd is a  detail that will become known once I tell her  story, which has changed a  bit as well because of Thenos having  interactions with her now  throughout their lives, and I'm sure I'll  have to change a few more  things as other Advent players really detail  out the Advent way of  life.  It's no big deal.  I know why she does  things the way she does.   Right now at this point, it doesn't make  sense on why Roesh would pull a  gun on her during their first move into  DS (early in my posting)  considering how much he appreciates her  work and protects her, but  something I've never had the opportunity to  go over which I will be is  how they resolved their uneasy trust and  Roesh's current level of  parenting to her forms...  And it involves  Roesh pulling a gun on her.
       I go back occasionally and read my older stuff and think about  how  these things make perfect sense to me, but to the rest of you,  there's  no reason for it, and to some degree it almost appears  contradicting.   So I'm going to start making steps to correct that.   Plus it will help  the reader understand the characters better.  Just  like Teal has gone to  great lengths to give us all a detailed  understanding of her character,  her state of mind, her emotions, and  it's just damned good character  development.  I've done similar with  all of mine, however, just never  taken the opportunity to make it  known.  I didn't give myself the luxury  of starting from the beginning  and working to the current point since I  was more eager to get involved  in the current story since I had already  wrote the other stuff once  before.  That ultimately could be a downfall  in my story, however, I  believe that as long as the effort is made to  fix it, then in the end,  everyone reading will see the character  development and be all that  much more appreciative of the characters  themselves.  The trick for me  is where to put them into the story.  I  don't like just dumping them  into the lore.  Doing so would take away  from the story as a whole,  however, adding in flashbacks at the  appropriate times builds a story  up even more, and that's what I'm going  to strive for.
      My civil war is a good starting place for that.  So far all  of  my characters have stayed out of anything but minor conflicts while in the DS region.  This   civil war will be exactly that.  A war.  The old governor has been   quiet for too long, uneasy tensions are building, and I got to portray a   bit of that already with Riona.  I don't want to drag it out and hurt other   people's RP's but my system is going to get hot, it's going to get   violent, it's going to get ugly.  But I always have the ending worked   out before it ever starts.  It will end up being better off for having   gone through it.  Like relationships in general.  Sure it's nice to   always agree, but we all hear stories of people who hate each other,   just being at each other's throats, they always have the strongest bonds.    Opposites attract, and conflicts are healthy.  The same thing could be   said about a story.  Without an antagonist, the protagonist is just   another character.  It's always the villain who defines the hero, but   not always.  See the Batman/Joker relationship.  The hero created the   villain.  An idea that is just so different from the norm, an idea that   hardly ever works out, it was done so well that the characters stories   are known worldwide by people of all ages.  Yet to repeat it is   extremely difficult, because by definition, the hero is incapable of   creating a villain.  Bad creates good, not the other way around.  I'm   trying to recreate that same effect.  Roesh and Henry are not heroes,   but they're far from villains, yet I hope I've done things right so that   I can have them be the cause of this civil war by just trying to do   what's right.  It's been a long time in the planning, and it's taken a   lot of participation from outside sources.  My 'good guys' have   essentially created 'bad guys' and now they're going to have to deal   with the result.  Don't get me wrong, I'm not trying to pull off the   Batman thing in popularity or scale, I'm just seeing if I can pull it off  period.   I've been told I have a talent for deviating from the norm in  story and  art, but these aren't my passions in life so I never really  build on  them.
      I'm not joking when I say I have looooooots and looooooots  of  history.  Unfortunately, my story here is kind of like George Lucas   telling the story of Star Wars.  Movie wise, he started off with chapter   4 and went to 6 and stopped.  We all knew there were 3 earlier  chapters  even though we never really had any hope of ever getting to  see them,  and there have been several dozen different stories since.   Yeah we did  get to see 1, 2, and 3, but even those didn't really cover  everything he  originally wanted.  Time line wise, I'm forced to start  in the middle  of my story even though it begins a half dozen years  before the Vasari  invade.  Currently I'm in like chapter 5 if you want  to keep the  comparison going, and this civil war is going to get me to  start  reaching back into the first 4 chapters.
 
 
So that's my current predicament and thoughts on character and story development, and I know other writers have their own thoughts as well.  Best thing I can do for us all is just say post your problems here and accept whatever advice you can get.  =]
