Scobleizer discusses here how Halo 2 is using RSS to track game stats. I don't have the game or an Xbox to play it on, but I like to play games on occasion, and it is still really interesting to see how this technology is being put to use in this form. Personalized statistics are reported from the feed that are specific to the account of an officially registered Halo 2 player. I read the brief post linked to by Scobleizer and did my own research on the Xbox live and Bungie sites as well, and it seems pretty cool. Though, I think I'd have to be a really hardcore gamer to fully appreciate all the detail offered. It makes you wonder how common RSS will become in online videogames as gamers become accustomed to the individualized stat reporting in Halo 2.
