Ever since my wife recently got us iPhones, I've been using it more and more to play games. So far I've downloaded the following:
 
- Tetris
- Call of Atlantis (Match 3 Puzzle)
- Around the World in 80 Days (Match 3 Puzzle)
- Rebirth of Fortune (Tactics)
- Transformers G1 Awakening (Tactics)
- Secret of Monkey Island SE
 
The puzzle games are great, the tactical games are good, but a bit awkward, and Monkey Island isn't too bad in this format & still a lot of fun to play. So, can any of you out there reading this recommend any other great iPhone games & don't say "Angry Birds".
