I'm coming in a bit late, but I've now officially signed up for the Gamerscore Challenge to raise my Gamerscore by 1500 in the time period between February 12th and April 12th. Hopefully there are some prizes left by the time I finish. Doesn't help that I'm starting with a handicap: 11 days late to start and my current GameFly games are both for the PS2. Maybe it's time to load up Dead Rising again and remind those zombies who's boss. Wish me luck.
