For those who haven't heard yet or need a reminder, today marks 15 years of Xbox and its killer app that launched alongside it, Halo. So take a day to reminisce through mystical forerunner world, battle your buds in arena combat, or just anything Xbox related. Myself, I've decided to do a legendary run through The Maw, and experience the great warthog run once again. So tell me, what are your celebratory plans?
