how many FPS games DON'T have a mediocre single player?

[ph4nt]

I would say Half Life 2 and CoD 4, Perfect Dark.

Every other FPs i have played (including Halo 1-3, Gears 1/2, CoD 1-3, Resistance 1/2, etc.) have had abysmal single player games.

Halo 1 had a ton of potential for a great single player, unfortunately none of it was used.
