i agree with wut most of most of these guys say
Halo Wars isnt like the rest of the Halo series, it is a strategy game, like umm....Age of Empires, or ya wutever..... but it does look pretty good, actually very good, the graphics look amazing, so personally... i would buy it....but at $80, thats a lot... so i would wait until the price dropped a little, but not too long... maybe $50-60, anyway......
if u want the original Halo feel, wait till Halo:Recon other wise known as Halo:ODST comes out.... in that game you play as a regular soldier, so this time you dont have a 10 000 pound shielded armour guarding your a**, so its a little harder, so you have to be a lot more carfull, kus in this game, you cant take as much hits as Master Chief can.......but ya....the graphics for that game look freakin amazing...
but its your choice.... you can buy Recon, or Halo Wars... or both!!!
me personally, definately both... im a huge fan of the Halo series... and i want to experience both of these games.....
i hope this helped......good luck on your descision
