Rockstar Games announced Red Dead Redemption: Game of the Year Edition:
Red Dead Redemption: Game of the Year Edition is rated M for Mature by the ESRB and will be available at retail stores in North America beginning October 11, 2011 for $49.99.
It includes everything they have released so far (read: all of their DLC). If you still haven’t played this game, I highly recommend it. Might be my favorite single player experience ever.
