I've recently found myself actually wanting to do quite a bit of PSP gaming, what with the Persona series, Tactics Ogre, Valkyria Chronicles and quite a few Final Fantasy games available on the device. However, I really can't stand using my PSP: it's uncomfortable, and has pretty awful battery life. I've been thinking about getting a Vita, but the only game on the horizon I can really see myself buying for it is Persona 4: Golden--the rest would be supplemented by PSP games I never got around to. How do PSP games play on the Vita? Do they format to the screen well? And, most importantly, can the device be held for long periods of time without hand cramps? Should I buy one now, or wait until the Golden comes out, hoping for a price drop in between?
