Re: Editing GA *end* dates?
GA is notoriously unmoddable, but it wouldn't hurt to try. I would suggest adding the "SetGameEndDate:: 1205" line to your EARLY.txt file and see what happens.
Re: Editing GA *end* dates?
This is an amazing idea, i believe if the game ends with GA the faction with the most points wins even without filling up their bar, so an earlier start date should work. This would be amazing as Count said for early or high campaigns, to make an end point before victory/world domination is inevitable/long since actual. If anyone does this let us know as it would be great for providing a conclusion to a campaign while it's still fun instead of grinding it out towards 60% or abandoning it.
Very interesting idea indeed.
