I think what we have so far is sort of an open beta. Once the dev kit is fully released in November we'll probably see more content each week.
For me the service right now stands between heaven and hell. The prices aren't as low as the Play store to lure impulse buyers and the lack of trophy support is doing nothing to attract the hardcore crowd to the service.
SCEA should really start contacting high profile devs like Capcom, who are notorious to have a large variety of iOS games while ignoring Android, to port their games to PSM. This way, devs can enforce some reasonable DRM on their products (PSM) while Android users get exclusives that would otherwise not be available in the platform.
Add trophy support and other features like cloud saves and Sony could have a new stellar service. But again, this makes too much sense, so it probably will never happen.
I see a bright future for PSM if done right.
Needs Trophy Support..this will reel in alot more gamers in!
IOS devs would love it with the addition of touch screen and physical buttons, it will bring much more broader and deeper games.
Know what would make PSM actually worth it? If Sony hadn't pulled PSOne classics from tablets. What benefit does PSM provide me at this point? The library is small, the functionality isn't stellar, and pretty much any game found on PSM will end up in the Google Play store for cheaper.
Sony really dropped the ball, and I'm sure they have their reasons (like trying to give people a reason to buy the Vita), but it seems like they keep making one terrible decision after another when it comes to the mobile gaming market. You've got people who are willing to throw their money at you, in order to play PSOne games on their phone or tablet, and instead you'd rather release hardware failure, after hardware failure, in order to stem off the devaluing of your brand.
At this point, I can't see PSM having any longevity, and it's a novelty at best. Get your head in the game, Sony.
