RPGs IMO. The PSP carved out a niche market in the West and a mainstream one in Japan by attracting a lot of medium tier Japanese RPGs. In the last generation, the PSP's RPG library was second to only the DS, trailing it very closely.
However in the 8th gen so far, Sony seem to be losing some of that support; Atlus have been supporting the 3DS much better (EO4, SMT4, Soul Hackers and an announced Persona vs Persona 4 Golden) and Falcom have stated that they will be supporting the 3DS, in contrast to how they skipped the DS. Sony somehow need to reverse this trend. Given the fact that both Gust and NIS are both Sony orientated, if I were Sony I would get they to throw their weight behind the PSV and hopefully help inspire others to do so.
