Whats the longest game you have played?

for me. witcher, on hard!

WoW as it never ends until the devs stop releasing big patches. But non-MMO? Probably Fallout 3 with DLC, 200+ hours.

Including MMOs then WoW

Otherwise Rome Total War, Medieval 2, then Baldurs Gate 2.

Everquest.

Fallout 3

for me. witcher, on hard!

CloudSnap

WoW easily. Over a year in /played time across all characters combined.

Outside of WoW? I'd say either Battlefield 2, CSS, MGS2, RE4, all of those Ace Attorney games, or DA:O (I swear it seemed like that game was never going to end. It got boring half way through) I don't think I could pick just one.

My experience would probably Fallout 3 GOTY or Oblivion GOTY w/90 hours each for one character..After mods & replays it's endless.

(excluding multiplayer games too I assume)
