Most MMORPG and JRPG games.

As far as single-player games go, probably none. I spent a high number of hours on Final Fantasy and Elder Scrolls games, but I don't think I ever crossed the 100-hour mark.

If we include multiplayer, then games like GoldenEye, Super Smash Bros. Melee, and Double Dash!! would definitely make it.

Recently only 2:
Xenoblade Chronicles (Wii) 180+
Goldeneye 007 (Wii) ~110

I move from game to game kind of quick, usually I finish the main story, play some rounds of multiplayer (co-op or competitive) and then go to the next one.

MAG, Uncharted 2/ 3, Killzone 3, Starhawk, and Dawn of War: Dark Crusade.

I think the only games I have payed for 100+ hours have been Skyrim, FF VIII, IX, X and more than likely soon to be X HD

Call of Duty Black Ops II(~220 hours), Halo 4(~310 hours), Final Fantasy XII(more than 1000 for sure), Skyrim(~150 hours), GTA V(~120 horus), Dota 2(just crossed the mark of 100 hours), Age of Empires II(more than 500 hours for sure), Pokémon Black(999:99 :P)...

Dunno what else.

Over 500 hours on Skyrim and over 160 on PKMN White 2. No idea about previous gens. But willing to bet most PKMN games are well over 100 hours

How do people manage over 100 hours on OoT or Majora's Mask?! Or any Zelda game for that matter. I get "overall" if you've replayed the game, but I don't know how anybody could clock up 100 hours or over on 1 play through. My first play through of OoT comes in at 19 hours 100% completion!
