According to the ESRB website, Sony Computer Entertainment America (SCEA) has a total of 15 new PSP titles in the works. Most (if not all) of the games appear to be downloadable efforts, considering the simplistic quality of their descriptions; however, these games are unlikely to be part of PlayStation Minis, as they are rated exclusively for PSP (Minis are playable on the PSP and PS3).
ESRB is the entertainment rating system used in the US (PEGI for Europe), familiar to most gamers and parents. In order to educate parents about the rating system, SCEA are integrating a guide into the PSPgo device. The built-in guide provides a overview of the rating system and a step-by-step walkthrough of the device’s parental control features and settings.
