Massively: I remember the first time I got hit hard by the powerhouse slugger known as "burnout." It was during my second stint in World of Warcraft, oddly enough, which by then had extended to a year and a half of solid play. I was clocking in three to five hours of game time on a daily basis (this was my pre-children era, obviously) and enjoying the cruise up through The Burning Crusade's content.
