Not only games, but also graphs/charts. I'm colorblind and I can't remember how often I had to understand a graph where the lines were in red, green, yellow and / or orange. And the specific colors were chosen so that they - to me - pretty much all look alike. Then I have a look at the legend and can't figure out which is which and the whole point of the chart is lost on me.
