A disabled gamer who goes by the name iwasasgoodasany vents his frustration with games that don't allow button mapping. I have often felt the same way and I have full use of my hands! I can only imagine how frustrating it must be for this dude. I understand not all games (Kinect, Wii, Move) can be made more accessible but there are a vast number of games that would be if they allowed simple button mapping.
Warning there's some NSFW language in the video.
