Halo should not be in the list. Or half-life/ bioshock should be and must be above Halo.

Oh and also, Portal instead of Doom 3.

The add of Metroid Prime and Dues Ex is a +10 for you, though the absence of Goldeneye gives you a -100.

 even your list sucks.... GoldenEye 007 has to be on the top 10 no matter what, same with Wolf 3D.

The bolded should not be on that list. Italic is an either or not both.

I would have chosen other ones.. Half Life 2 number one....And Halo would be a lot lower...The only thing that I really like about Halo is the Theme...

@ Kratos: Portal is more of a puzzle game than an FPS, I think.

@ ArtOfAngels: As much as I hate to admit it, having spent countless hours of my youth playing it, Goldeneye really hasn't aged well. The framerate is awful, the lack of a second analog stick hurts the controls, and the muddy, blocky visuals are almost painful to look at. There's a great many better shooters out there nowadays.

@ ssj12: I know you're biased against console games, so the fact that you bolded every console-exclusive FPS on that list isn't exactly unexpected. Also, SS2 and Bioshock are sufficiently removed from each-other (the latter is just the spiritual sequel to the former, and not a direct sequel) that I see no issue with listing both. Finally, Wolf3D, like Goldeneye, hasn't aged well at all; it's basically an FPS in its most basic form, which really isn't anything to write home about nowadays.

Yea, I have some issues with that list. The original Half-Life should have been on the list, Doom 3 should not have been there. I've played every game on that list. Duke Nukem is a humorous inclusion but it wasn't anything too special, just funny.

Games that should have been considered.

Descent (how the hell does this game get missed when talking shooters, yes you were in a ship but it wasn't a sim game. It was an FPS with full range of motion)
Shogo (has everyone but me forgotten about this game?)
Unreal Tournament
Battlefield 1942 (how did this game not make the list?)
Tribes (the first open battlefield online shooter)
Half-Life

Games I agree with:
Call of Duty 4
Wolfenstein 3D (how can you not, really)
Halo
Half-Life 2 (although I kinda want to swap it for HL1)
Golden-Eye (but not at #1)
Counter-Strike
Quake

My list:

10: Tribes
9: Halo
8: Unreal Tournament
7: Quake
6: Battlefield 1942
5: Golden-Eye
4: Call of Duty 4
3: Descent
2: Counter-Strike
1: Half-Life (game of the year 1998 but was still selling for $30 in 2003. Half the game was the game itself and the other half were the mods. HL mods are still played in great numbers.)

I'm not mentioning Wolfenstein 3D anymore on a top 10 list. It gets the honorable mention of being the father of all FPS games. It was a very basic game that started it all. I don't want to try and apply standards to it. It is the immortal father of FPS.

 I give their list a 9.3.

that list fails for lack of Unreal Tournament

Mine would be something like:

10 Call of Duty: 4. Modern Warfare.

9 Half Life.

8 Timesplitters: Future Perfect.

7 Halo.

6 Wolfenstein 3D.

5 Quake 3: Arena.

4 Counter Strike: Source.

3 Doom

2 Goldeneye.

1 Half Life 2. 

---

Noteable mentions: Metroid Prime, Deus Ex, Team Fortress 2, Portal, Duke Nukem 3D, BattleField: Modern Combat. 

WTF? Doom 3 makes the list, Half-Life and Doom 2 don't, and GoldenEye gets number one?

I often wonder what those Screw Attack boys are smoking when they compile these lists.

 I generally leave Doom off of my list.  Once you even consider Wolfenstein 3D, then Doom is just an upgrade with a BFG.  It does have the BFG though so I guess that should get it added somewhere.

I give that post a 9.6.
