You can all have your Halo 3 if you want but I don't give a damn, the 360's true killer app for me is Xbox Live Arcade. The below interview reveals a ton of info on this great feature, with games priced at $5 or $10 (approx £3.30 and £6.50 for the UK) and old classics updated with HD and online multiplayer (with voice chat aswell) this trully is an awesome. Microsoft aren't just using this for old classics either, it is an outlet for indie developers all over the world, so the lack of variety and innovation that plagued the Xboxes catalgue is ridden with one fell swoop. Please just read the interview and I'm sure you'll be just as excited as me.
