I never thought about how color blindness affects gamers. David, Glitchy, are yours the typical red-green color blindness?
No, mine is a bit more advance. But different. I can't tell similar shades from each other. (It took me awhile before I could barely tell that the background of the other one was different). So no, it's a different type of color blind, but it's affected me in some ways. For example, if anyone has played Pokemon Diamond/Pearl, they know the dance parts in the Super Contests? Well, I believe that there are two different colors on the left and right sides for buttons you need to press. I've always messed up on this because...well, both look the same. Causing me to do it from memory, which messes me up. Thats only one example of how it's affected me.
