Do you know any games that mostly require one button to play? Just pressing buttons, without holding. I want to connect Wii Remote to PC and map its shakes to one key - to help my disabled student make rehabilitation a little bit fun.
Totem Destroyer is sort of one button. Same with Prince of War. Actually, not really. It is arrow keys, and space. And then send units with your mouse... I still think it's pretty simple though.
Unfortunately, he won't be able to play any of games mentioned above... Some require holding button or moderate timing skills, or moving the cursor... Aren't there any simpler games? Like Canabalt for children/.
