I love you commander Fox.
Just so you know, the sales for PC would be horrid, most liely ever game will get sold, but people are not going to buy a computer for a game, they would rather buy a 360, and MS gets more money off the other games. I bet every person that buys Halo 3 will buy Halo Wars because it has Halo in it's name, and a crowd nerly half that size will buy a 360 fir it, Halo 3, and Halo Wars, plus a bunch of other games.
This is just about sales though, but if they made a PC version of Halo Wars, it would not only ruin the game, but it would DEVISTATE the Halo franchise, the quality would absolutly SUCK! They would have to make the same game twice in the same amount of time, imagine what that would do to the game.
