As confronts an identity crisis in the face of waning game and the popularity of competing portables, the number of games available for digital download is a problem for prospective PSPgo sales.

Sony remains committed to releasing its own PSP games on UMD and for digital download on the PlayStation Store, but third-party publishers aren't forced to do the same. That's causing problems for PSPgo because many games are simply not available for the handheld.

A report by GamesRadar highlights Konami's decision not to make some of its games like Silent Hill: Shattered Memories available for download.

While many publishers do offer their games via the PlayStation Store, the fact that not all are on board casts doubt on the portable's future.
