GalCiv is a space 4X game...yeah, I get that. What I think would add a lot to the game with a minimum of recoding (easy for me to say) is having the ground attacks for each race show a little diversity. Nothing overtly crazy, just have each races units, and jawa trasnports (thats what they look like to me) be unique looking.
I know its a small part of the game, but Its been stagnant for far too long IMHO
