I bought Burnout paradise from Xbox Live, and have bought all the additional DLC's. But when I am not connected to internet, it wont launch at all? So I can't play offline. Can anyone help me, or explain why this is?

Definitely Assassins Creed 2

It's great for those who have only one Internet cable :)

I heard the most recent update to xbox live was to prepare it for facebook/twitter etc. So I guess soon
