The #1? I have to say Zelda, it's the only game I played which really got me into the story-line. And I kinda like peacefull, cute and happy things. So yeah, that's my #1.
#2 would be
Marathon (scroll down), dang that game 0wned. Very complex story-line, really made me think like "Huh?" sometimes, usually I found out what was going on 2/3 levels ahead.
And the #3's gotta be
Escape Velocity (
Override), I played that game for hours straight, nice gameplay, it's gotta be the large universe and endless amount of missions in the game which made me play it for that long. I eventually ended up cheating, hacking the game's memory (with some program) making it think I had about 500 photon turrets on my ship and conquering every planet. (including the pirate's, mUhAhA)
(btw can't wait for
part 3 )
Anyways, most of you don't even know #2 and #3, they're mac games. I'm just answering the question ;p
