World at war was a much more thought out title than MW2. IW obviously put stuff in their online because it sounded cool and didn't test it fully enough to understand half their additions would be used for pure evil...not to mention it's gotta be the most easily hacked game of all time. Ten year olds are hacking it! It's fun but definitely a flawed game. Heck, in Treyarch had the initiative to make it so you can't fire off noob tubes to spawn tube in SnD.
