This week, PlayStation Mobile rolled out on the PS Vita and PlayStation certified Android devices, offering users a curated selection of optimised games while filtering out all the App Store chaff.

That was the stated intention, anyway.

Back in June 2012, SCE head Jim Ryan claimed that PlayStation Mobile users wouldn't "stumble upon any of the junk that exists in the wider marketplace."

To be fair to Mr Ryan, PlayStation Mobile is not full of junk. In fact, there are great games on the service – one of which I've already lost hours to. However, it's not an unblemished selection, and this is the problem.

Sony's vision of a curated store that's exclusively populated with gaming gems is already undermined.

For the platform to succeed, Sony needs to keep that quality bar stringently high. When you're competing against established app marketplaces, there's no value in offering a small selection of mixed quality.

Perhaps this is the inevitable consequence of requiring games on the platform to be developed in C#. After all, it's a relatively small group of developers that will be willing and able to make that effort for PlayStation Mobile.

If Sony's hoping to play curator, it will need a sizeable longlist to choose from if it's to have any hope of success. But that's quite enough of my wittering – let's move on to our bite-sized overview of the last seven days' worth of news.
