How could you forget games like Cod 4, Bioshock, and Halo 3. But you put bulletstorm and Crysis 2 when they're just average fps games. But I would go with Killzone 3. I got the game on the first day and I still can't let go of it. It can keep me busy even longer than Gears 3 comes out. No offense your list did forget some really epic games be sure not to disinclude games like Halo 3, Cod 4, and Bioshock next time you talk of the best FPS :)

Killzone 2

Battlefield Bad Company 2

I wouldn't count Bioshock as an FPS, as it's much bigger than that imo.

Also how Portal can be called an FPS is beyond me. It's a puzzle game.

KZ3...MP is soooooooooooo much win

Bioshock is a really straightforward shooter. It should definitely be classified as an FPS. The plasmids are a nice touch but there are loads of FPS games that offer similar mechanics (The Darkness is a good example).

best one will probably be remebered as call of duty 4

as exclusives go, u cant not pick halo3/reach even if you dont like halo games

I was actually going to say that including The Orange Box in the poll isn't fair, because it's not a game, but three games. (And damn good ones, at that.)

Then I saw that it actually isn't winning.

You're blowing my mind here, VGChartz.

Bioshock easily takes the cake as the best singular FPS in my book, though.

COD4..the most sublime blend of balance, maps, and great SP...God, how i miss 07-09 so much.

1° Bioshock 1

2° Far Cry 2

3° Orange Box

And hey... Bulletstorm? Really?

I enjoyed Metro 2023 and Bioshock the most. 

Have to give it to the Orange Box, almost seems unfair to count it as a single game, but then it was the same price as all these other games new so I guess it's fair if you think about it that way.  

I never got into TF2 but just having Half-life 2 and Portal is enough for me to vote The Orange Box for this poll.
