And like you mentioned, Scribblenauts.
Then.... theres Zelda, Megaman Starforce 3 and Drawn to Life: The NExt Chapter (I thought the concept was great though gameplay wasn't as good... they seem to have improved on the formula and etc.). Theres really many good games coming out. It just matters if you want to wait or not.
