Sticker star is not an RPG. In fact it's whole premise is adolescent. There are no RPG elements in Sticker star.
Persona 4 on the Vita is getting 98 out of 100 reviews while Nintendo is still hammering out dumbed down little kid games instead of real RPGS.
Persona 4 is rated M and it is awesome with a real story.
Interesting. What makes you think a game is mature, aside the ESRB M rating? (which doesn't actually mean a game has mature content, only that it has a bunch of visual and auditive cues that people recommend not to let children near it)
Devil Survivor Overclocked (and most MegaTen games) have more mature content than more than half of the M-rated stuff out there.

Alright Devil Survivor Overclocked is also a remake so that's probably a moot point.
Tales of The Abyss, Denpamen, actually I can't think of too many that are currently out besides what is coming out (Fire Emblem, SMT Soul Hackers, SMT IV, Monster Hunter (sort of), etc). That's still more than what the Vita has going for it.
