Im not sure exactly but I put a good 2 to 6 hours a night for  years on Midtown madness 3 on the original xbox. I imagine I have to be up at around 3000 hours for that game.

I had over 200+ DAYS (not hours, DAYS) in WoW for 3 years. Oh my early, geeky 20s lmao...

I think I have Fire Emblem: Awakening at 455 hours at the moment.

i need to reactivate my wow account and have a look.

but for sure its over 100 days

World of Warcraft = 3 years and a little more, (i play the game since it was released but no 24 hours 7 days a week)
Super Smash Bross Brawl= 2782 hours.
The Elder Scrolls V:Skyrim= 682 hours.

Planetside 2= 652 Hours.

Starcraft 2 (with expansions)= 584 hours.
Diablo 3 (w/ expansions)= 356 hours.
FF Vll= 182 hours.

No idea how long. But the longest time I played one game was Jedi Outcast MP. I played that for 3 years, everyday.

Though it doesn't have a counter or any track of time, I have over 2500hrs on minecraft xbox 360 version alone. I have also spent over 2000 hrs on Skyrim on Xbox 360.

I guess none here have played MMOS my main character in wow have over 2 years logged in.

woot?

over 1000 days playtime?

not bad. i quit after burning crusade

Highest is probably Battlefield 3 with about 320 hours.
Place 2 should either be Monster Hunter Tri with a little unter 200 hours or Fire Emblem: Radiant Dawn (don't know how many hours but played it through about 10-12 times)

i expected a pokemon title from you mister kapi:P
