Urm, lets see...Atelier, Gundam breaker, Trails of cold steel, neptunia, disgaea, god eater, etc, etc. I've bought at the very least over 30 titles in total to use on mine?
If you're into the sort of niche anime-centric RPGs that are MAYBE ported outside of Japan by the likes of Nippon Ichi and ATLUS, alone, then the Vita had some games for you, but the combination of a serious lack of games outside of Japan and the mind-bogglingly terrible online service (where Sony eventually just gave up and told people to download games to their PS3s and PS4s and THEN transfer it over to their Vita to actually play a game) devastated any chance at real market share outside Japan. Meanwhile the DS was eating Sony's lunch while stealing Sony's girlfriend.

It's basically the PSP all over again. I have around 20 imported VNs and dating sims on my PSP as well as some RPGs as well.
