Modern Combat: Sandstorm N.O.V.A. COD Zombies Uhh there are some others but I'm lazy. They aren't console quality, but still some of the best quality iPhone/iPod Touch games you'll get.
Modern console quality: GTA:CTW Chaos Rings In my opinion no other games on this platform come close in terms of console quality. CoD Zombies would as well if there was more meat to it, but there just isn't enough there in my opinion to add it to the list.
Like what everyone said, chaos rings, gta, and pretty much and 3d gameloft game: avatar terminator salvation hero of Sparta dungeon hunter blades of fury etc. also doom ressurection need for speed resident evil 4 street fighter 4 FIFA

Tony Hawk's Pro Skater 2- I played this on a friend's device and found it to be surprisingly good, pretty true to the original outside the soundtrack. Rayman 2- I had this on PC,but never finished it. Ignore the bad reviews, I was able to beat the game for my first time on the iPhone. Driver- Never played this one on the consoles, but many people insist it's a great port of a great game. As far as console-like games go, just about anything from Gameloft will do.
No particular order: - Jet Car Stunts. - Battle For Wesnoth. - GTA: Chinatown Wars. - CoD: WaW Zombies. - Eliminate. - Skies of Glory. - Chaos Rings. - Baseball Superstars 10. - Zenonia Series. - Defender Chronicles. - Hook Champ. - Inotia 2: Wanderer of Luone. - Puzzle Quest CHP. 1, 2, 3. I feel these are all solid (and must have) choices to have. Best of there kind...
