I grew up on the console, but progressed to the PC later on. These are my favorite games, so far:
Half-Life: and all the other evil incarnations of it (CounterStrike)
Starcraft: Yea.
Diablo II: Somehow refreshingly addictive.
Alone in the Dark: I was just a 'lil kid when I watched my friend play, and twas scary.
Grand Theft Auto 3: Got boring after a while, but still addictive when it wasn’t.
Castle of the Winds: Watched a friend play, it was funny, for some reason.
That’s all I can think of now…
