Sony has unveiled a new initiative for PlayStation Portable games to attract new talent to the system.

PSP Minis will be small digital games for the handheld and be limited to 100MB in size, and retail for a lower price than normal titles.

"Minis allow many developers who have never developed for PSP before to do so for the first time. They offer smaller, downloadable games at low prices," confirmed Andrew House, European president on Sony, at Gamescom today.

15 Minis games will launch on the PlayStation Network on October 1, with 50 titles promised before the end of the year.

As well as publishers such as Electronic Arts, studios including Gamehasta in India and Halfbrick in Australia are also developing titles.
