im not a fan boy of any of the two companys (IW & Treyarch) so I enjoyed all of them

but my thoughts on the games are
MW2 - didnt quite live up to what i thought it be, but I never complain about the game. (just wish the AUG A3 was in it lol (the gun in my avatar pic)
MW - great game and the best FOR ITS TIME <- key words there lol
WaW - I loved this game, ppl complain cos its all been done before, but thats not a bad thing. The guns, the blood, the game modes (hardcore FFA & such), kill streaks were NEW and the levels were pretty well made. In my opinion it was a good game. not to mention WaW had the first stickys IW took the semtex idea fae that
Ths post is not ment for arguing, just an opinion.
