Betrayal at Krondor - still the best RPG to me. Morrowind comes second.

Elite - Spent far too much of my youth on that
Bards Tale - The first great RPG
Tac Ops - Much better than CS
Civilization - I still go back and play it after all these years

Counter-Strike will always be a great.. still playing it after 3 years..
Current fav. Hands down, Battlefield 1942, can't get enough

championship manager 4. Best sports managment simulator out there. I just like the challenge of bringing a local shitty team from England or Italy all the way up to UEFA Champions. Although I've yet to succeed with this new version yet...I'm trying.

Earthbound, for those who have never heard of it it was a really unique RPG that takes place in a modern setting.

Freelancer in multiplayer definitley you can always have fun on freelancer wit your friends. My second favourites are the entire GTA series and Call Of Duty

almost forgot Red Alert 2, Vietnam, RCT2 and tiberium sun
