Best first-person-shooter game?

I thought Halo was alright to be honest. Nothing exceptional. It was the the fact that you were constantly running through the same corridors that ruined it. Needed more variety. Other then that, gotta say I kinda enjoyed it. Nothing memorable though, save for a few levels.

Going by the demo of UT2004, I enjoyed the heck out of that game, just mindless shooting. Hopefully when my PC problems get sorted, I will be able to enjoy the full game properly too.

But like I said previously, Chaser is the only really good FPS from the last few years. Since Deus Ex anyway.
