What is the most Hours you ever put in a game?

[marvelvscapcom2]

Mine is 38 days in Call of Duty Black Ops III. .   Its actually my favorite of the franchise. I loved the latest one and I am excited for Inifnite warfare even though the reception by fans was bad. I may have put more than that into Pokémon Yellow over the years. i used to no life it when i was a kid. and have beaten it maybe 10 times. but i don't remember the exact time spent.  I got a little too hooked on Call of Duty though to an unhealthy standard. I am glad I stopped when I did.   

What game did you log the most onto?

1800 + Hrs into GT5.

Probably Elder Scrolls IV: Oblivion. I got 100% achievements on XBox, and I completed like every single guild/group storyline and the main one, as well as both expansions. I don't know how many hours I put into it, exactly, though.

31 days on Red Orchestra 2 / Rising Storm

Impossible to know. It is only a recent thing that we have ways to measure how many hours we have a game open (Steam measures this, not actual activity).

I played Diablo II multiple times a week for 8 years.
I played Quake 3 Arena weekly for over 10 years.
I've been playing Major League Manager (Baseball simulation game for DOS) since 1992-93. Its almost mind boggling. I currently play maybe 10 hours a month, been on a monthly schedule since around 2008. Before that, I can't say. I can remember playing it every day, and also can remember not playing it during the off-season. In the 90s, I played it usually during the baseball season, sometimes even following along the then current MLB schedules.

about 550 hours into Pokemon Heart Gold 

[pacpix]

500+ into RuneScape over the years. Doubt any other games come very close

[bikingjahuty]

Probably around 150-hours in my first playthrough of FFVII. That included getting everything and beating every extra boss, except Ruby Weapon, he is impossible.

3000+ hours in Pokemon X and Y I have multiple copies of these games but I have 3 copies where the timer is maxed out. (Stupid shiny hunting).

[blurks]

658 well spent hours in CoD 4 Modern Warfare Multiplayer. Such game, very fun.

[kashell]

Nearly 500 hours in Star Ocean: The Last Hope -International-

EDIT: I thought of a few others.

I probably clocked at least 150 hours in SaGa Frontier.

I went through Final Fantasy Tactics about four times, which probably totals to about 200 - 250 hours.

Finally, I've lost track of how many times I went through shorter games like Mega Man X4, Chrono Trigger, Valkyrie Profile, and so on. But, I'm sure by now with all of my times through these games that each one has well over 100 hours.

[kamikazekeeg]

Don't know how much time I put back into World of Warcraft or Star Wars Galaxies back in the day, but the only one I have numbers for at the moment is 644 hours in Team Fortress 2.

I don't know exact numbers, it would probably be Monster Hunter 3 Ultimate though.

[parasiteadam]

Fallout New Vegas (big surprise right?) Hours logged on steam 220's. Add in my playtime while deployed while playing offline I'd have to say somewhere over 4 close 500 hours.
