Speaking of balance, Dave and Colm's UI (user interface) is coming along swimmingly and almost every single option is now incredibly easy to use and find - although with increased features comes increased complexity. Trying to make the navigation of all that stuff simple, is an enormous challenge. One odd thing about the UI is that Halo 2's UI actually gave us a tricky little legacy. The Live and 360 hardware guys liked our "Y" button so much, they apparently modeled the big silver Xbox Live guide button after it - in that it instantly pulls up your profile, friends and settings menu.
