And I played Halo 2 on Live for years and I am pretty sure it never put me against a pc gamer, and if it did I couldn't tell. Once again, a gamer would have to specifically perform some sort of LAN bridge to plain against pc users which would just be plain stupid. Also, Halo character movement is a lot slower than pc designed fps so hitting your opponent is much much easier. PC FPS games are known for jumping like bunnies, but that doesn't really work well with Halo since character movement is not as fast.
