Sony's PlayStation line of game systems has been a leading brand for third party developers for more than 20 years now. After famously stealing Nintendo's thunder with the original PlayStation taking all the well known third parties with them, Sony has enjoyed the backing of some of gaming's top developers. Even less successful console's like the PSP and PS3 still got enough support to hold their own against their competition. But there's a big outlier in the PlayStation pantheon that could make even a lackluster Nintendo console blush, and that's the PlayStation Vita.
Vita is the red-headed stepchild of the PlayStation franchise. It's impressive hardware and cutting edge visuals couldn't save it from a terrible memory format, bad marketing, the rise of smartphone gaming, and as a result, poor sales. Because of all of these issues, third party support was unusually weak for a PlayStation console. When the system first launched in 2012, it showed some promise. It got ports of popular remasters from the PS3, and even ports of actual PS3 games to go with it. But once the realities of the system became apparent, everyone who originally backed the system, began to move away. Thus, after the first year, Third party support for the Vita dwindled to near non-existence, as developers began focusing on the much more attractive PlayStation 4, which would launch in NA, just a year later. It didn't help that Sony didn't bother making games that could make up for the lack of third party support, as much of their output consisted of watered down PS3 experiences. Unless it was a niche, no-name Japanese developer porting over a PS4 game, most major third parties dropped the Vita as quickly as they took it up. You know third party support on a PlayStation console is bad, when you can't even find a GTA game for it, let alone when not even Square Enix releases much of anything for it.
It wasn't all bad though, what the Vita lacked in mainstream third party titles, it made up for it with a solid library of indie titles that lended well to its handheld nature. In fact, it was a better indie machine than it's competitor, the Nintendo 3DS at the time. Nintendo Switch may be the newest indie darling machine now, but I think the Switch owes a lot to the Vita regarding how to really court indies.
PS Vita could've been something great, and had Sony not been incompetent, it could've actually made Nintendo bleed in the handheld market, and possibly be the first system to actually bridge the gap between Smartphone gaming and console gaming like the Switch is now. But Sony had to be Sony and once again, force proprietary media down everyone's throats, barely release compelling games, and not even market the damn thing properly. I can't say I'm surprised nobody wanted to make games for the Vita.
