just like a few have already asked, total time or in one go?
got about 55 days playtime on my main character on WoW, and if someone thinks that's alot I'll have you know that it's since the launch of original WoW back in 2004 (I think). I'm a pretty lazy player...
In one go is probably Fallout 3. Not counting the ~15min dinner-break I'd say it was about 18 hours. About 12 hours if that break counts.
um any cod game online i usually play 4 like 10 days for both w@w and mw2 so those are my top games and thats not even offline or single or coop game modes
well longest time i've played a game mainly was either starwards battlefront 2 for the ps2, ratchet dreadlock for the ps2 (got so addicted to that i became the 50th best wrencher), or waw/mw2. longest game played strait was probably mw2
Total game time it would definatly be Dragon Age: Origins. Beat that game nearly a dozen times and each playthrough is 24-34 hours long. You do the math :P.
If I had to count every pokemon game I played in the equation it'd without a doubt be pokemon. If it's an individual game, I'd have to say some NIS game. My present game on Makai Kingdom's at something like 500 hours.
