Goldeneye will win something like this because people remember how much fun it was to sit around with their friends in the same room and play the game. I agree, it was a blast! However, if you take any of the other games and play them in the same room with your friend, I think the results would be very different. Or alternatively, if you take Goldeneye and only play it with people over a network, it would suffer a lot. The point I've already probably overblown is that a good chunk of the fun of Goldeneye was smacking your friend upside the head when he/she got you with a proximity mine. Beer may or may not have played a role depending on how old/what access you had.

And I agree with an above comment; if System Shock 2 was on the list I'd have voted for it. For those only familiar with Bioshock, to make that game they took everything that was great about SS2 and removed it. Except for atmosphere, they did keep a cool atmosphere, though that's debatable since not everyone liked that part of Bioshock.
