The Playstation Portable, while far from a failure, has not reached the same audience as its competitors. Despite having an install base of over 70 million units sold, PSP games never quite seem to sell as many copies as they should.

This opens the door for a lot of great PSP games to not only get remastered in high definition, but also reach an audience who might not have had a chance to play them. Here are the quintessential PSP games that deserve HD remasters.
