PS3 vs Xbox 360 FACTS
The Xbox has a better, meaning larger, online community.
The PS3 has better hardware in it, thus the better graphics.
Flaw of pretty much every online community: Immature children. They're EVERYWHERE. They've even invaded Team Fortress 2! I hadn't seen any children running around calling people fags, but then I joined a server, and it happened to be a children haven. It was horrible.... Modern Warfare 2 is full of children. It is not possible to join a server/host that doesn't have atleast one child under the age of 12.
Annnnway, my PS3 thing is: d1sturb_
