...not the trial version? Hi, I have played Call of duyy, Wolfenstein Enemy terriotory, Halo. I like them but the thing is that i just LOVE HALO!!!!! but it is only a trial version (sucks) but i wana play halo where i dont have to pay for anything and play the full version and samething for call of duty full version. SO I ONLY WANT FULL VERSION, NOT WHAT PEOPLE SAY TRY THE TRIAL. And if you there isnt any full version for free then are thier any other better war games simaler to call of duty modern warfare or halo? and also how do i download grand theft auto to my computer? Thank You
