I've had this game since the day it came out.  What, about a year now?  Anyway, I very much enjoyed playing the single player game through.  After I completed it, I set it aside.  Coming back to it, it's still the second best game in my collection  (Deus Ex is hard to top).  If you enjoy FPS games, then you should give this a try.  It's a cut above the usual Doom and Quake type shooters, as you are allowed plenty of flexibility as to how your character performs in the game.  You are given upgrade points, and can put them towards whatever attributes you want..  which basically means you can play the game in a number of ways.  You aren't really given the freedom that a game like Morrowind or Deus Ex gives you, but the game does ask you to think about what you want to do, and it accommodates your decisions better than most games.

However, after coming back a year later, the single player FPS part of the game isn't what keeps me playing it.  I'm addicted to the Light Cycle races, now.  The light cycles are the most innovative, hyper, and fun thing I've seen in a game in a long time.  I'd rather play Light Cycles than buy Half Life 2 at this point.

Overall, this game has a lot to offer you.  It isn't the kind of game that you'll stop playing after it's done.  With the multiplayer and light cycle modes, you shouldn't be done with this game until the sequel comes around.
