What I think is if someone get's the Live version of the 360, I think people should be able to play together on the live, and instead of the computers being on the live version there could just be a bunch of people on the live version, making battle more intense, trading better and such. But yeah, that's just my opinion...Right?
In line with the PvP I wonder if it is possible to make a co-op mod. Something along the lines of a LAN mod, not an over the Internet mod. I think crawling around the dungeons and in Oblivion with some friends on a LAN would be awesome. Just my 2 cents.
