I wasn't aware that there was a community built around console games. You can have a friends list, maybe even a website, but that requires that you have a PC too. That doesn't compare to being able to hire a server and create your own content. In fact these gaming threads suggest to me that many Mac owners should really have bought a PC. The cases aren't as pretty but better performance can be achieved at much lower prices. Even though my PC could run a tonne of stuff in the background I choose not to. You never know when one of those programs might decide to update, or do an autosave, and then your game might stutter. Music is just a distraction, as are IM programs. The resources of an anti virus program these days are usually next to nothing, and if you aren't gaming online, you can shut them off anyway.
