Scooby-Doo! Who's Watching Who (PSP)

Scooby-Doo! Who's Watching Who (PSP) ... starts out with a themed hub world, and from there you collect Scooby dog tags to unlock three sub-levels. These levels are divided into an Investigation stage (generic platforming), a Driving level (crashing into walls with the clunky Mystery Machine), and a Chase sequence (falling into holes you can't see). The point of each level is to find clues strewn about and solve that episode's mystery. These clues can then be analyzed by Velma via a series of frustrating, unpolished mini-games. When you get enough dirt on a suspect, you can try to catch them by setting off a series of traps when they walk under them (such as pushing a cannon on top of a suspect). The Scooby gang plays for keeps.
