Eternal Gaming.

[Spinozaad]

Baldur's Gate II.

 

[Eliam_Dar]

Half Life 2, is just that good.

 

[ProfessorLayton]

Maple Story. I've spent countless hours on that game and it's really the only MMO I've ever played if you don't count RuneScape which I played for about 3 hours and quit.

 

[The Maddest March Hare]

WoW, Allods Online, Oblivion. Any MMO or RPG that could be filed under "lifesinks". I don't even play WoW, I just know if I did and could afford the damn sub fees I'd probably never see the light of day again..
