Out of that list, starcraft and half-life are all that I really like. I voted starcraft...
Do not make a poll on favorite game, unless it's between a few, because honestly, you're rarely going to find everybody's favorite game on a poll.
Some of us love Metal Gear Solid (myself included), Diablo II, Halo, and too many others to bother naming.
My favorite game of all time is Doom and Doom II.
