I've read on other posts that GalCiv3 does have cheat codes.
1) How do you enable them?
2) Is there a list anywhere?
My use of cheat codes in GalCiv2 was always to make the current game better. I loved using the code to play as the computer race. When I came across an opponent that had the potential to do well, but wasn't making the proper choices, I'd take him over and "point him in the proper direction." If this involved colonizing a planet or two for him, so be it. I often turned minors into "pseudo-majors" that way. I had a game where the Akilians had 5 systems. It added a lot of flavor. Thanks all.
