i think inchworm animation is pretty cool. it's not a game per se, but it allows you to draw anti-aliased with some really good detail and cool effects. plus, you can animate your drawings like a flipbook, take photos and draw over them. you can layer stuff so you can try and draw over a photo without actually editing the photo itself... 4.99 and it's pretty cool whether you're an artist, like to doodle or even just want an extended notepad to write in. flipnote studio is supposed to be coming free, but i've heard inchworm is way better.
