I really liked Zubo personally. It's a rhythm based RPG with gameplay elements similar to Elite Beat Agents. It's visually attractive, charming, and fun. The story is almost nonexistent, but the game is fun.
Soul Bubbles. An excellent 2D game with you blowing a giant bubble around levels. You draw a circle around a group of spirits and are supposed to guide them through lush and ambient levels to the end of the level. Gorgeous, relaxing, but challenging in later levels. And no, you don't really blow into the mic in the actual game, just control the blowing by tapping near the bubble. A sleeper hit and a great one at that.
There's also Star Wars Clone Wars Jedi Alliance. Personally, I thought the gameplay could be better. Amazing 3D graphics and fully voiced lines, but the stylus controls felt a little laggy and repetitive. Still, some people like it and it gets good reviews. Might want to try it. It has some action sequences spread around the game similar to Dragons Lair. They require touch based actions to complete acrobatics and such.
Maybe I'll remember some more later.
