Most hours logged into a game?

187 Days on 1 character on Wow... I had 2 other level 70's and countless other alts...
 
This was all Burning Crusade era though...

I have logged 1,628 hours and 21 minutes over the last 50 months in Guild Wars.

diablo 2, i spent countless hours in that game killing the same enemies to get better gear...

I've very easily logged 3,000 hours into Counter Strike.

300 hours in Pokemon Diamond, 100 - 200 in each of the other pokemon games, around 180 in San Andreas and 120 in Fallout.

150 hours in Fallout 3, over 100 in Oblivion.

A little under 2000 hours in Counter Strike: Source (No, that's not a typo). After that its probably about 800 in TF2. In terms of just single player though, either GTAIV, Fallout 3 or Persona 4, all of which have 100-200 hours clocked.

World of Warcraft easily.  Probably 40 hours a week for two years.  Yeah, that's why I quit. :-)
 
For non-MMOs, I'm sure I've put in around 300+ hours into KOTOR since I played through it several times.

"Do MMO's count? I've got about 1,000 hours in Guild Wars, probably even more than that in Runescape. Yes, I play Runescape, but I've played it since day 1 when it was a cool indie MUD, and not the 12-year old fest that it is today (albeit it's still a great game for anyone that gets into it).  "

San Andreas, probably. like 300+ hours in that game. i played that game to fucking death  
 
EDIT: that was just on the PS2 alone. on PC i got in over 400 hours (still playing it alot, too!)  
 
here's some proof:  http://www.xfire.com/profile/ajayraz/

Diablo 2: I spent probably about 300+ hours on it in total; I go in on/off phases of playing every year.

Over half a years worth of Super Smash Bros Melee.
 
Am I winner?

4000 or so hours into World of Warcraft.

It's either Oblivion (thanks to mods) or GTA: SA. Then again, FF7 may be close contender due to the times I had to replay it. Or maybe Deus Ex, or Alpha Centauri?...

Including all the expansions, I'm sure I've passed at least 1000 hours of Dawn of War 1. Dawn of War 2 is slowly creeping up on it and will probably take the throne one day though.

6000 games of halo 3, times roughly... 8-10 minutes per game? equals... 48,000-60,000 minutes, equals more or less something between  800 to 1000 hours of halo 3. I wonder what it would be if i added up halo 2 into the mix as well. 
 

If MMO's count I spent aprox 5000 hours on World of Warcraft, maybe more. I don't regret any of it though, I had a shitload of fun with that game.

I don't want to know how many hours I have put into Halo 3 multiplayer 
 
And I know of people that have put 180+ DAYS into Runescape in the span of ONE YEAR!!!  Said people need to be shot.

450 hours of left 4 dead, that game is great with friends on versus.

Diablo II
World of Warcraft
 
 
 
I can't honestly say how much time I've spent with them.

WOW. Actual game time is 30 days 16 hours and 24 minutes

1,689 Halo 3 Games played  
 I have 32 campaign games we will say those are at the least 30 so thats 960 minutes 
 1,248  Ranked and Social games (added together) we will say those are 10 minutes so thats 12,480 minutes 
Custom games tend to last longer than ranked games and  I have 409 of those so I'll say those are 17 minutes thats 7158 minutes (I rounded up) 
So that is 20,598 minutes which is (Drum roll please) 343.3 hours...that's not counting all the time I played campaign and 1v1 matches Before Xbox live. 

120+ on Smash Bros. Melee.

its a toss up between ocarina of time which i played through 100% several times and pro evo which I have played a disgusting amount of over the years.

Probably either Age of Empires II+expansion or RollerCoaster Tycoon+expansions.  Hundreds of hours over several years went into each of those games.

How can this thread possible have gone on for this long without the mention of Monster Hunter? I must have spent at least 200 hours on MHP2 (PSP) and then more so on MHP2ndG! And I'm a light player of that game. 
 
I do have about 13 days in Call Of Duty 4 though.

" I must've played Enter the Matrix for easily 100 hours. "

I've never looked at totals, but in one sitting it would be Planescape: Torment - 60h non-stop ending with ultimate satisfaction and a severe case of insomnia. I prepared myself for this baby, then I sat down and nailed the hell out of this bitch. Considering how rad this game was, I'd do this again.

What?? How? Didn't it have just a shortish single-player and no multi-player?  Probably TF2 for me. I would have no idea how many hours though. Up there in the 200's. "

Oblivion 300+ hours.

I've been playing Warcraft 3 online almost every day since it came out in 2002. You can do the math for yourself but it probably rivals that of a serious WoW addict.

Definatley Baldurs Gate 2, i would guess somewhere around 400-600 hours.

team fortress 2 for almost 300 hours, theres another previously mentioned game which i probably played closer to 1000 on but that huge waste of time just depresses me

Outside of the 60 or so days I logged in WoW  before I stopped playing, I'd have to say I spent the most time with Fallout 3 or CoD4.  I have about 90 hours between my two Fallout characters :P

444 hours for oblivion, that's when I hit the so called 'megaton' glitch that happens in that platime window, Even then I wasn't done with half the guilds or more than 2 quests ahead in the main questline, so I reverted back to a save 70 hours earlier to to catch up with those.

" I've probably clocked in (no joke) about 250 hours on GTA: San Andreas. "

" Almost 500 fucking hours with oblivion. I still cant believe I did that with a single player game. "

According to Raptr, my most played is Call of Duty 4, with around 200 hours. I would say San Andreas though - probably around 500 hours on that game.

Probably my 240+ hours on Pokemon Platinum, but I did play Halo 2 alot back in the day.

I have about 200 hours between several characters on the Elder Scrolls IV: Oblivion (120 hours on one of those characters).

the age of empires series and the cod series
