Which FPS series has the best single player campaign?

You and Boutros have my vote and support here. Half-Life was a revolution in terms of gameplay, pacing and storytelling and implemented the grandfather of quicktime events in a non-cheesy way and did it seamlessly. The music was raw and sublime and the game was even fairly big and sported incredible AI (for the time). When Half-Life 2 rolled around, it did the exact same to the genre in many of the same areas in addition to being a stellar technical achievement (the Source engine still lives and breathes and still kicks ass, Left 4 Dead 2 looks amazing on my rig) and the title that shot Steam into the masses for real and started the most brilliant digital distribution venture to date.

Holy hell, I just realized just how poor those other franchises are in comparison.

I would like to add that Call of Duty 1 and 2 had fantastic single player campaigns but the rest of the series drag the overall grade for the franchise down by miles (Modern Warfare was good though).

Have you played Bioshock?
