[Sinker sucks]

hard to believe that 90% of these answers are games from the last 3-4 years.

tempted to say Chrono Trigger is the most fun I've had playing a game.

depends on the mood I'm in what I would call the best game at any given time though. would have to be between:

Chrono Trigger
Crysis (1)
Shadowrun (original)
Morrowind
Dark Souls
Rogue Squadron
Titan Quest (Immortal Throne)
