If you somehow have time to take on a new open-world game in this insane fall release season, Sleeping Dogs
is nice and cheap on Amazon
right now. The PlayStation 3 and Xbox 360 versions of United Front Games' Hong Kong crime game are $40 on both retailers' sites, with the PC download version available for $30.
If you picked the game up now, you'd be just in time to start in on the new DLC
due this month.
