The boss of Sony Europe, Jim Ryan, has revealed in a recent interview with GamesIndustry International that his company's PlayStation Mobile service will avoid the usual app store "junk" by only offering PlayStation quality titles.

If you aren't familiar with Sony's PlayStation Mobile (formerly PlayStation Suite), it's a service in open beta that offers PlayStation-branded software to Sony Ericsson and HTC smartphones and tablets.

"[We're] ensuring that anything that is offered on this platform is of proper PlayStation quality," Ryan said. "People [will] feel comfortable and safe that they are not going to inadvertently stumble upon any of the junk that exists in that wider marketplace."

The PlayStation Mobile SDK is freely available to all software houses, and 50 developers are currently creating content for the service.

"It's a significant business challenge because it's our brand that's at risk here and it's our responsibility as a platform holder in multiple directions to ensure we do that. Can we be completely laissez faire? I don't think so because then we'll end up just like all the rest and that can't happen," Ryan added.
