939 hours in GTA V. 99 hours in SP, 840 online.
252 hours in Mass Effect 3 multiplayer.
268 hours in Metal Gear Solid Peace Walker plus 300+ hours from a previous save, which was deleted.

I think about 600 hours or so on Skyrim, thats its.
However, I have a friend in school that has played over 14,000 hours on Terraria, which I think is crap.

I know I put in a lot of hours on Everquest for the PS2, as I played it practically every day for around 3 years. One of the few games with recorded times I remember is White Knight Chronicles, with 417 hours. I also put something like 300 hours into Final Fantasy XII.

Probably pokemon yellow. I played hundreds of hours, starting over and making new teams. The time only increased when I got pokemon stadium that allowed me to play faster.

Hmm yeah..

Main RS Character - 398 Days (2005-2011)

Old School RS Main Character - 59 Days (Still Active [2013-Present])

OSRS Ironman - 10 Days

Final Fantasy X, RuneScape, Club Penguin, Street Fighter II and Super Smash Bros. Melee are probably my most played games.

Twilight Princess +1000 hours on the Wii version.
Have not played that version since a years ago.

FFX Valkyria Chronicles Def Jam fight for New York 

Some of these gametimes are absolutely insane! Don't any of you have jobs to go to or school or anything!? lol

Anyway! I've probably broken the 100 hour mark on a handful of games in 20 years of gaming.

I got about 130 hours out of Dark Souls 1. I probably got over 100 hours playtime out of Final Fantasy XIII as I finished it on both the PS3 and 360.

I'd guess that about the lot. If we are talking games that I've invested perhaps 50-100 hours in then you could probably add the following:

Driveclub
Final Fantasy 7
Grand Theft Auto 5
Red Dead Redemption
Zelda Twilight Princess
Persona 4 Golden
Castlevania SOTN
Fallout 3
Bloodborne
Fable 2
Far Cry 3
Dragon Quest XIII

Thats probably about it.

Well, I'm not exactly sure. The game doesn't keep a record since everytime you restart it, the time goes back to 0 hours played.

But it is Fire Emblem Radiant Dawn on the Wii. A normal playthrough will average you about 20 hours. I've restarted and played the game over the last 7 years more than 50 times by now I'm sure.

So if you do the math, we are looking at about 1000+ hours on one Fire Emblem game.
