In recent years, PlayStation Mobile has mostly been seen as an odd bit of branding on certain Android phones which promises a console experience on your tiny screen. Once a platform for interesting indie title, it's become a dumping ground for games which more properly belong on the Google Play Store. And now the service is kicking the bucket.
The PlayStation Mobile store will close on the 15th of July 2015, meaning no new titles and no access for existing users. More importantly, you could also lose the games you've already paid for unless you download and score them locally before the 10th of September. You'll also have to make sure your account on mobile orPS Vita has been activated before that time, as per this post, by going into the system settings. If you don't do that in time, you'll never see your games again.
It's a shame to see any kind of outlet for smaller games developers disappear but Sony never really seemed to get a handle on what PS Mobile was for. The platform was rarely pushed out in any meaningful way, and even the attempt when you bought a Sony Mobile handset felt halfhearted. With the availability of more Indie titles on the regular PSN store, it always seemed like a place for curious rather than high quality games. Losing the service entirely seems extreme though, couldn't it be folded into PSN in some meaningful way rather than losing hundreds of games to the abyss?
Right now that isn't going to happen, so enjoy your last few months with PlayStation Mobile.
