I curious. All you xbox users that have had halo since the xbox came out. Do you all still play it? I'm curious about its lasting ability. I've heard it is a great game, and everyone loves it, but does it have replay-ability? (its a simple yes or no question, I don't care what PS2 or Gamecube users think. If they don't have an xbox don't bother to answer just to start a fight).
