The only game I recall spending a great time is Pokémon Pearl, with a bit more than 550 hours.

Hmm... that's like 1000 hours per year on average in this gen, split between only 5 games (equals 3 hours a day which is doable but then you'll have to add some hours for all other games).

How certain are you about these numbers? Like Condemned, Oblivion and FEAR.

My only really big game is probably Guild Wars, with over 2500 hours. Then there is Warcraft III, which was the main LAN party game for a very long time, which is almost the only time I played. It's probably more than 100 hours spent on that.

Killzone 2: 325 hours or so according to my profile, could be 400. Don't think I played other games longer, maybe counter strike source.

If I've played 325 hours I think you should have played killzone 2 way more counting all your accounts bbh lol.

Any wrestling game i play at least a good 1000 hours. And thats at least. WCW MAYHEM i think i have played 1at least 4000 hours. seriously. I used to play that game all day every day. And then i played it for at least 7 hours a week for a good 7 years. and i still play the game like at least once every 2 weeks for like an hour at least.

Apart from that it would have to be Sims 2 3 have lost many hours on them games and the Total War series

singleplayer:
Final Fantasy IX (PS1) - 80 hours
Disgaea 1 - 80 hours (55 on PS2, 25 on DS)
Disgaea 2 - 150 hours (120 on PS2, 30 on PSP)
Tales of Vesperia (Xbox 360) - 120 hours
Super Smash Bros. (N64) - 100 hours

multiplayer (PC):
Warcraft III/DotA - 1000 hours
Heroes of Newerth - 300 hours
Counter-Strike - 200 hours
Team Fortress 2 - 140 hours

Wow, some of these numbers are crazy big.  The most time I have spent on a game is Pokemon Blue.  I have played and restarted and played again, so I'm not exactly sure how many hours I put in.  250 to 300 maybe?

This generation my highest played game is Brawl at about 100 hours.  I don't live near the friends I used to play it with anymore, so I haven't played it in awhile though.  They got a Wii recently though, and I forgot to ask if they picked up Brawl...

*runs off to Facebook*

Rough, rough estimates:

Mario Kart 64 > 300 hours
Super Smash Bros. > 300 hours
Age of Mythology > 300 hours
LittleBigPlanet > 300 hours

Super Mario 64 > 200 hours
The Legend of Zelda: The Ocarina of Time > 200 hours
Demon's Souls > 200 hours

Super Mario Bros. 3 > 100 hours
Pokemon Yellow > 100 hours
The Legend of Zelda: Majora's Mask > 100 hours

Only other games that comes close are Twilight Princess, Pokemon Diamond, Final Fantasy X, and a few other RTS games.

off the top of my head

I thought that too, but when I looked my old 2 accounts had little playtime.

And my BBH account had a little less than you, so 350 is about right.

But you did 325 in over a year, I did about 250 is 3 months
