Definitely Tilt to Live. Doodle jump was up there for a while though until I hit a bit of a 'high score' ceiling.
Puzzle Quest now that the IPad version is out. I will finally beat this game! Others are Sword of Fargoal, Book Worm, Plants vs Zombies and Monster Dash. Three games that I could not put down until I beat them are - The Deep, I Dig It and Space Miner. Loved all three of those games.
Stardunk. Add me on GC, I'm still shooting for that 10 friends achievement. Sushi Boy is damn addictive too, thanks to unlockables. Oh and anything by Halfbrick.
Just go to plus+, add random people on the leaderboards, once 10 have been added (they don't have to add you) get achievement, and delete.
very overrated, I find it pretty boring. I wish as many people got Red Conquest instead of that game..sigh.
i couldnt stop playing megaman battle of the network 2 for gba. I must have put in way over 200 hours just getting everything. and I mean, everything. I wouldve kept going with hard mode, had college not come into my life
I loved that game/series too, until it went downhill after MMBN3. I think this topic is for iPhone games only though. I'd say Game Dev Story.
