Another rumor concerning Sony's PSP Go is spreading across the 'nets: an app store for the PSP Go with shockingly low-priced games! Awesome, if true...

According to Pocket Gamer, games will be priced from 1,2 and 5 Euros per game. It doesn't say, though, if these games are old titles or new games.
