When COD began, yes it was less casual / took skill. As the game progressed, game design took a mass appeal approach. The gunplay for every weapon along with other game mechanics became simple and casual. Basically the only difference between a good anda bad playerin modern COD titles is situational awareness.

Anyone who thinks COD isn't casual has never played Counterstrike or Unreal. Halo also manages to not be as casual dueto the fact that you must get headshots with semi-auto weapons. In COD, every weapon is extremely powerful and recoil is nonexistent. Considering that body shots are effective enough, COD has basically taken all skill out of the gunplay.

Heh, both versions are the same price. $60

You might want to take that fan off of it, all additional fans etc siphon the 360's power supply. This leaves the 360 with a sparatic power level for essential functions.

Mass effect looks great and very very deep, but Halo 3 just adds so much stuff. I mean seriously, four player online coop, new weapons and vehicles, recording, forge,armor customization, etc etc etc. I think alot of people would like Halo 3 not to be GOTY just because it is so popular. IMO, bioshock only has atmosphere and story. Halo is great in that they integrate weapons with vehicles while being online.
