Halo3 about 240 hours , followed by halo warsabout 160 + hours, gears2 idk how much and GTA IV 100+ hours and fable 2 80+ hours

cod 4: about 70 hours
dragon age: 54 hours.

the game i put the most time into is frozen throne playing dota but it's not a game from this gen.

Modern Warfare 2 probably not sure how many hours exactly

World of Warcraft. somewhere in the thousands of hours.

other than that i would think its Rune Factory: Frontier at about 100 hours right now.

In fact, i think WoW might be more than all other games combined since WoW launch.

Warhawk; my profile says I played over 400 hours.

I can play that game for like 5-6 hours straight and never get bored. So many fun moments especially when the two teams are trying to capture the middle base in Archipelago.

Offline it's probably a toss-up between Oblivion and Fallout 3. I'd guess Fallout 3 though, by a hair.

Online, I'd say Gears 1, then Gears 2, then MW2. Though I've played a lot more MW2 lately.

Socom Confrontation and Left 4 Dead 2.

Mario Kart Wii.

I just looked up at my playtime records the other day and it says that I've played it for 799 hours. You'd think that I'd be better than I am at the game. You really would.

World of Warcraft by a long way!

1000s of hours I'm ashamed to say!

in final fantasy 11:online i am over 3k hrs, about 300hrs short of 4k.
