Off the top of my head I really like Monster Dash, Charmed, Wheeler's Treasure, Chop Chop Runner, Bird Strike, Battle Bears, Fruit Ninja, Superblox, GeoDefense, Karnival, but gosh there are so many more that I enjoy.
I have Dodonpachi Resurrection but i have a fricken iPod Touch 2G...is there a way to make it work without buying a new device.
