I'm sure I could think of more but here are the ones on my iphone: The Sword of Fargoal Game Dev Story Galaxy on Fire 2 Crimson Gem Saga Spider: The Secret of Bryce Manor Battle for Wesnoth War of Eustrath Battleheart World of Goo Space Miner Real Racing 2 Grand Theft Auto: Chinatown Wars

Order and Chaos Zenonia series Crimson Gem Saga Real Racing 2 Dungeon Defenders: First Wave Puzzle Quest 2
I spent more than that on some pretty good endless games that are so addictive: Tilt to Live Silverfish Doodle Jump Infinity Blade Fruit Ninja
as a friend, I suggest you need to take more rest especially when you are young (one of my teachers told me)
Zenonia 2 Doodle Jump Fruit Ninja Tiny Wings Infinity Blade Tetris Death Rally Chaos Rings Dungeon Hunter 2
Hmm, great question. Off the top of my head I would have to say; Boggle (Yes I'm lame...) Defender Chronicles Game Dev Story Hot Springs Story Annnd, that might be about it. The problem is that I just don't have the time to invest in most long term games, which makes the mobile market perfect for the quick play games.
Rogue Touch Dungeon Raid Angry Birds Warblade (40 hours, 12 Minutes, 53 Seconds) Orbital Field Runners WSOP Lootwars (such a great game that got discontinued)
Emross War Rogue Vertex Online The Quest Gold Super Quick Hook Crimson Gem Saga Wild Frontier Maplestory: Thief Edition Knights of the Phantom Castle Game Dev Story Hoggy Robot Unicorn Attack: Heavy Metal And soon to be: Doodle Army 2
hmm... I love Cover Orange, but even with 190 levels I don't know if I have spent 20 hours on it. I played Final Fantasy 1 for a long time, crazy penguin catapult 2 also captured my attention for ever.
