I know nothing of modding tools or what you,re up to.
GalCiv3 is certainly not "long in the tooth". It's just about to hit puberty with second expansion.
Stardock's stated intention is to support and expand this product for several more years. Expect a seven year cycle, from release providing it maintains sales.
Don't expect a IV before 2020. Too much unrealized potential in the 64bit engine now.
Well now...with this being said...I got plenty of time to work on this.
With games sometimes only lasting 2-3 years, and I apologize...I should have done my homework. I just looked it up & GalCiv2 was released in 2006 and GalCiv3 in 2015 so you are 100% correct. GalCiv3 is still a "baby" with a long way to go.
My goal is a windows app that will be run outside of the game to be "user-friendly" in modifying the appropriate XML files and make it easier for people to create a game to their liking. As I said, it's not hard to open and edit the xml files...if you know which ones to edit & what xml elements to edit. My windows app will take the guesswork out of that.
Launch the editor, edit to your hearts content, save files, open GalCiv3 and enjoy your newly modded game. Quite honestly if it gets used or not used by anyone else is not a big deal. I'll use it and learn more about C# programming and xml files along the way. Win-Win for me. May as well share it with the masses if someone is interested in it.
Thanks for the info, Go4Celerity! Much appreciated!! +1'd your karma.
