Everyone that has been waiting for a reason to buy a PSP — your time has arrived. Grand Theft Auto: Liberty City Stories ($50) now has a release date — October 25 — and it looks to be one of the hottest games this fall. In LCS, you follow the path of Toni Ciprini, a mob boss returning to town after laying low because of your implication in the murder of a rival boss. Interested yet? Then how about the fact that this Liberty City is as big as the one in GTA III.
