Right, this is starting to get really jaded now, and would be a problem for Sony, if it cared. Anyone taking a look at the Vita chart will see old games littering the place and a crippling lack of new releases. If you were picking one up then there's still lots of solid names in the list, but it is feeling its age now.
With Minecraft the only major release until Autumn/Winter (Freedom Wars October, Tales of Hearts R November), its not going to get much better. And to think, this is quite a decent list, compared to Spring when very old (even launch) games dominated. So while indies may keep the userbase playing, the wind down to obsolescence continues.
