I must (respectfully) disagree. Bootcamp is a boot manager much like Grub, it allows the user to select which OS he would like to boot. I'm thinking that Bootcamp does create a "fake" MBR to placate Windows NTFS, but otherwise the Apple hardware is, for all intents and purposes, just another Intel based PC.
Perhaps you're thinking of Parallels, which is indeed virtualization software and a very poor environment for running games.
