Games You Just...Can't...Put...Down.

FATE...won't...let...me...go...!

Addicted to Fire Emblem: Awakening.

civ and garrysmod :)

Both Mafia II and Euro Truck Simulator 2 have had that effect on me.

Rogue Legacy.

SRIII

Hard platformers, generally. I ragequit, wait a few seconds, then open it again. :(

Mass Effect and Organ Trail.

Euro Truck simulator 2, i keep getting back for more

I haven't found such a game so far. I get bored too fast. Anyone got suggestions for can't-put-down games?

Need For Speed Underground

Rogue Legacy. New Game+4, everything unlocked, and I'm still playing it.

Any COD game

X-COM, Dishonored, Half-Life (1,2,Black Mesa)

It's not so much a game but the steam application in general atm. Got so many new games from sales i cant decide what to actually play....

I have Gabriel Knight series, Mass effect series, Fable series, Quest for glory series, Theme hospital and The movies installed all the time, just in case :)

Skyrim: 480+ hours on Xbox 360, 210+ hours on PC... (:P)

Metro Last Light did that, but Fallout New Vegas and Skyrim had that effect on me for a while (but they're RPGs so they don't really count!)

I like fortix 2, counter strike 1.6 and portal 2.
These are the games which i never stop playing them :D

Strike Suit Infinity, Ion Assault and Rogue Legacy keep drawing me in for more.

These days it's Firefall, it's shaping up nicely :)

Defy gravity extended badumtsssh

Minesweeper

Mass Effect, Skyrim and Fallout 3/NV are the worst for that :( And things like the Civ games or games in the same general "One more turn and I'll stop an hour later ONE MORE TURN I PROMISE...."
