Classic Game Room reviews the Sony PSP Go handheld video game console that plays videogames downloaded from the Sony Network instead of UMD discs. The new model PSP Go is smaller than the older 1000-3000 models and doesn't use UMD discs (which prevents you from buying used games) or work with the PSP camera and games like Invizimals and Eyepet. PSP go has slick styling, nice buttons and an analog stick as well as good battery life and an excellent screen. Screen size is smaller than older model PSPs though.
