It might be hard out there for a pimp, but Liberty City Stories makes it easier by bringing the immensely popular Grand Theft Auto series portable. Keeping tabs on your lovely ladies while building the Leone crime syndicate is as fun as it is impressive. Liberty City Stories packs the enormous urban locale onto your PSP in an amazing feat of game engineering. Although not perfect, it's hard to deny the pleasure you'll get from this stellar side-story.
Or, for your 80s fix there's Vice City Stories, which doesn't offer much different from its predecessor other than its tropical setting, but that shouldn't keep you from getting in on all the action. Exploring the crime-ridden streets of Vice City taking on action-packed missions is loads of fun, even if visiting Liberty City ought to be your first priority.
