YES. I've just bought the soundtrack a few days ago and am totally itching to play it again just for the music
TWEWY despite being primarily touch would be harder than you think. Do you know of anyone's finger that is the thickness of a stylus? Also the game was made for two screens and they would have to use up a ton of real estate just for controls since there's no d-pad or buttons to handle the top partner. Just because it's a DS game that uses the stylus quite a bit, does not make it a good candidate for the iDevices.
Eye of the Beholder Rise of the Triad (someone is working on this I think...) and Road Rash 2 FTW! (Tilt to turn/steer, tap screen to punch/kick/swing chain) +1 for Dungeon Keeper. Would also love to see a Vampire Action RPG like Vampire: Bloodlines (PC)
