1. Its a kind of backdoor program that helps you "cheat" in the game. Helps with testing mods.

2. It takes some logistic spots (4) and I think the deconstruct ability on your builders can help.  I think.

3. Galaxy Forge. Found in the downloads.

4. A good one with lots of planets and few opponents. You can also set up a game where there are no opponents. Just hit the continue playing button afterwards.

it still uses distance from home.  move your capital 1 jump from the star, and you should notice your fringe planets gaining allegiance.  Also, use culture. 25%-> 35% is a big boost.

answer to the second question is:depends.  go ahead and colonize it, prolly spam it with tradeports, but if its a rush game, and its a ice/volcanic, there is a large invenstment turnaround for those planets, expecially if you havent researched those techs yet.

Allegiance is determined by how many phase lines are between your homeworld and the target planet. If your homeworld happens to be close to the star, your other planets in other star systems close to their star will have slightly higher allegiance. I think.

If there are 6+ jumps between your HW and the planet though, the planet can only have an allegiance of 25% (max 35% with culture).

Well, you're playing AI, right?

Generally you've won the game once you've wiped out the enemy's fleet, at which point the AI will either surrender or you'll be able to advance and wipe out everything at will.

But when you fight further in enemy territory, you'll generally take more losses, and it'll take more time to replace your units. So except in unusual circumstances, usually you should aim to fight on one of the enemy's front line worlds if you're attacking.

If you have more cash than you need (which is often the case in the late-game when playing AIs), colonizing the enemy's dead worlds is often a good idea which can help if you want to move frigate factories or repair structures up.

Wrath89:Rebellion isn't out yet. You have Trinity (or Diplomacy) in which there are only the 3 usual factions of TEC, Advent, and Vasari, but Rebellion hasn't happened yet.

I was just asking if they had said anything

How often do you guys move your homeworld?  If I own two star systems should I move it next to the star?  I've never messed with it because once I get that far I've basically one the game, just need to finish with the fighting.

I only play multiplayer, so I haven't had to move my homeworld due to having too large of an empire. But I guess if you find a nice Terran planet close to the star you could consider moving your homeworld there after that star system is almost completely yours, but other than that it would probably be best just to keep your homeworld as it is. At that point in the game, most of your income comes from trade ports anyway: allegiance just doesn't really matter that much.

Your home planet should be where your primary planet-economy is, which is almost certainly in your original star system. Even if you never worry about relocating your HW, you probably won't be missing out on much of anything.

On the harder levels like Unfair and above, you'll be seeing the Fortifier AI build tons of turrets and other defenses on most or all of their planets, while an Aggressor will come at you with a larger fleet earlier (probably). I'm not sure about Hard but it'll probably be doing the same sort of thing, except with slightly less intensity.

On Cruel and Vicious though, I think the AIs play very similarly, simply because they have so much more income than they can deal with, so they focus on investing in everything.
