I only play casual games on the phone. Less than 10 min usually. Chess, poker, bejeweled, etc. Time wasters. And even then only when in low signal and can't browse.

Games of course look better on the iphone. Doesn't mean they play better because there are exceptions when a developer is too concerned with looks and not gameplay and there's also the lack of kb on iphone.

Far as i know, most smartphones have had such casual games for years. Still hard to believe Palm didn't have a few ready for the Pre.. That's part of having a palm.

Problem with iphone for any other type of game is that its a touchscreen with no buttons. If i want something more than a casual game, i'll use my computer or PS3.
