Your numbers are quite impressive, I can't bear such huge hours of playing, I get annoyed a lot of times !

GGrrreat :D - All of these are counted by the games = i'm not guessing (and i hate you if you did it)

Persona 3: Three playtroughs of 181, 304 and 96 hours (each one counts NewGame+) = 581 hours

Pokemon Diamond: 662 hours (would be -and counting but it has been a while now since i don't have a ds :(- ) (Only PT)

.Hack // G.U.(whole trilogy, it saves your play time from each previous game) : 276 hours and 121 hours (Two different PT's with different purposes) = 397 hours

And this gen Saints Row the Third : 78 and 31 = 109 hours

Don't have real registers of any other game where id put more than 100 so that's it.

Note: i still actively play these games execpt for PK Diamond for the already specified reason

Wii Sports: 300+ (never lost a match in tennis:))

Super Mario Galaxy also over 200h+

I probably put in 1000+ hours each playing basketball, baseball, and football when I was in grade school and middle school. Close second would be tag and hide & seek.

Oh, we're talking about video games?

GTA: San Andreas probably occupied 200 hours of my life cumulatively. I don't think I've cracked 100 hours in any other game, but Dragon Age: Origins and GT5 are close.

Well...

These play times are just estimates and are combined from multiple playthroughs:

Runescape - >1,000 hours
Arma II - 600 hours (got this in August )
Pokemon Silver - 500 hours
Call of Duty 4: Modern Warfare - 500 hours
Call of Duty: Modern Warfare 2 - 500 hours
Final Fantasy XIII - 250 hours
Final Fantasy VII - 100 hours
Persona 4: Golden - 85 hours (got this less than 2 months ago )

I'm sure there are many games missing that should have made the list, just can't think of them now. Some play times are complete estimates, for all I know, Pokemon Silver could be 200 hours or 1,000 hours.

Definitely GT5, over 1000+ hours

I also have 400+ in Dark Souls, 300+ in Demon's Souls and 200+ in Ninja Gaiden Sigma 2

P4G-200 hrs and counting.

right now...150 in Monster Hunter 3 U

so..you tryna hunt?
