half life2 and its expansion. Just a brilliant game
age of empires series (didn't play the last one though)
the C&C series
WoW
Diablo2
Rome Total War
I'm sorry son, it's already too late.I cannot express my joy that no one has so far mentioned World of Wankcraft.
Half Life 2 is up there. BUT, Ocarina of Time is the best, hands down.
Hmm...
