Say a game you plan to play for 30mintues then go do something else, but you end up playing the game for a couple hours with out realizing it.

MarioKart Wii

Mario both 2d and 3d mostly 2d though

Pokemon SoulSilver

Wii Sports Resort

Kingdom Hearts

Tatsunko Vs. Capcom- Yet I am still pretty bad at this game

Older FF gamesand a lot of other JRPG"s

Older Zelda games

A Boy and His Blob- For some reason I really like redoing the levels in this game.

Anyways enough for now whats yours?

all games pretty much, ESPECIALLY fallout 3...i wanted to play it for 2 hours, ended up doing like 7 0_0

Yea, I think I usually play games longer than I meant too, but there are some big ones.

Killzone 2 for sure. I just hop in a "Long Warzone" room and after 2 or 3 rounds, it's not uncommon that 5 hours have breezed by

Mass Effect 2- I just went over 40 hours last night, and it really doesn't seem like I've been playing that long.

FF XIII- I try to complete a chapter a day and end up spending hours and still not finishing chapters.

God Of War,MW2,is Fallout 3 fun?

Pokemon and Final Fantasy are the main culprits, aim to play for about an hour or so and 5 hours later im still playing. Oblivion was also like that, in fact most RPG's are, FPS's i dont spend very long on cause i get bored so they are the "safer" game to play xD

All the games i play, even if they're bad games =s

Any wrestling game

halo 3, halo wars gears of war 2 and battlefield bad company.
these are the ones i think of immediatly along with some XBLA like shadow ocmplex.
