Super Scribblenauts. Very addictive. I'm surprised at how good it is at recognizing things. I didn't expect that it will understand how to create the words black hole, virus, god, pneumatic drill, and beautiful titan. I can picture a similar system being used for a Green Lantern game that allows you to create almost anything you can imagine (just an RPG, of course. It wouldn't work in an action game or any genre that requires instantaneous creation of things).
