I loved GalCiv and played it quite a bit. I tried several times to play GalCiv2, but I never got very far.
Looking back (it's been a while since I tried it), I think the main reason was something very simple: I cannot tell the yellow and green squares apart on the planet map. It sounds like a little thing, but it made planet developing irritating--not fun at all.
So, is there a mod that changes the color of the squares so a red-green color blind person* can be tell them apart?
*for those not familiar with color blindness, I see color fine. However, certain shades look the same, such as bright green and yellow.
