Did you miss out on the Microsoft press conference yesterday? Leave it to Tara and Max to give you a video recap of what went down. Trust me, you're far better off just watching these highlights than going back and finding an archive of the full showing. Unless you are really into entertainment apps. You weirdo.
As far as games go, it sounds like Tomb Raider and Halo 4 were among the better ones shown during the conference, which I absolutely agree with. Both games demoed well, and even though it's become a running joke at this point, I still legitimately love bows and arrows in videogames.
