But Dragon Quest titles sold well on the Vita and they announced Dragon Quwst XI around that time. Vita has tons of first part support, those Assassin's Creed and Call of Duty games weren't free. Sony ported Borderlands 2 and Resident Evil Revelations 2 themselves.Years ago though.
When was the last AC game that came out on Vita? 2012
When was the last CoD game that came out on Vita? 2012
When was the last Sony first party title that came out on PSVita that wasnt a PSN legacy title (PSX, PSP, etc)? 2012
Even borderlands vita, a title that Sony had to publish because 2k didnt want to publish it was released in 2012.
5 years ago, the only lifeline that the Vita has now its just niche Japanese titles being announced but that support is dwindling thanks to the Switch, a platform that even if it fails like the WiiU is still expected to get first party support and more third party support considering it is Nintendo's main platform and sole future platform.
