A list that caters to young, shallow gamers. Hell, the selection and commentary exude my point.
The only games on their list that I agree should have been there were Duke Nukem 3D, Counter Strike and Goldeneye. Not including Half-Life (in place of Half-Life 2 and Bioshock), Team Fortress (in place of Quake), Starsiege: Tribes, Deus Ex, or Doom (in place of Wolfenstein). That they would put Doom 3 or even a Halo in the same ranks of the "greatest" FPS to me is, well, laughable. That's my opinion. I would always put the genre defining titles before the ones that incrementally improve the formula.
