It really depends on what gaming styles you like. If you like RTS (Real Time Strategy) games like StarCraft, Command and Conquer and/or Warcraft (not WoW) then Halo Wars is going to be awesome for you. And for all those who say that Halo Wars is being made for a loss of ideas, watch Inside Halo Wars on YouTube. You will see that Halo 1 was originally a RTS for the Mac, then it was transformed into a 3rd Person shooter and finally became a FPS. If you have Xbox LIVE, the demo for Halo Wars is coming out on the 12 (I think)
