Games I'm so addicted to: Project 72, CoD WaW: Zombies, geoSpark, Run!, and Droplitz. Best games ever IMO
The most addicting games I've ever played were Pac-Man Championship Edition, Let's Golf, Run!, and Flick Fishing.
MMMmmm Brains Jet Car Stunts had me locked in for a while... Then Pac-Man CE for a bit... I don't think any other game has sucked me in as much as PvZ and I normally don't even like those kind of games. The game has amazing charm. Really hoping for some DLC from Popcap. This game has me hooked! Just starting Space Miner now and early on it is pretty great too! Almost forgot about Labyrinth 2 and Space Invaders IG
Puzzlemaniak has been eating up between 20 minutes and a couple of hours of my day, almost every single day since before there was even an app store (there was a Jailbroken version). I often worked until 2AM on Ground Effect and then lay in bed playing it until 3 or so... I've toyed with actually deleting the app but made do with kicking the Player Challenge habit. I still play the Web challenges. This is like an alcoholic giving up beer but continuing to drink vodka... One other thing, what was wrong with the word "addictive"?
The games I have spent the longest on would probably have to be: Labyrinth 2 X2 Football 09 Jet Car Stunts Really good games, but would not necessarily call them addicting, just when i'm on my iPhone, I play them more than my other games.
