You still has SR1? I haven't beat SR1. I have every DLC except the map pack for multiplayer. XBOX live too.
Yes, I have both of them.
Unlike most people, I actually like to play games before their sequels.
For example, almost everyone in my school plays MW2.
Unlike me, only one or two of them has played CoD4.
But, the only one I played prior to that was CoD3.
