The Vita's latest updated Legend of Heroes RPG in Japan picks up a good score from Famitsu with a 33, while Shrien (an update on a Nintendo DS RPG, I think) does even better with a 34. There's a neat limited edition of Heroes with a figure, Vita pouch, cloth and audio CDs, which might help nudge sales along.
Shiren the Wanderer 4 (PSP) – 9/8/8/9
The Legend of Heroes: Trails in the Sky (Vita) – 8/9/8/8
I started playing the PSP version of Trails in the Sky, but got waylaid by Persona 3 Portable, I suppose I might get back to it one day...
