The most important difference is if I get teamed up with a bunch of rocket spamming whores and AFKs I can walk away and go somewhere else. Like a another planet. I'm not stuck running back and forth over the same map pushing the same buttons over and over. Seriously Bungie needs to show the masses you can turn around in the Demo and run off and do something else. Or walk along the wall instead of going through it. People are not really getting the how large this thing is.
