GamerTell has posted a very positive review of Atlus' Persona 4 Arena.
From GamerTell's review:
"There are plenty of special attacks and more savvy players will have to keep track of SP and, in the case of characters like Aigis and Naoto, ammo. At the same time, Arc System Works did everything possible to make Persona 4 Arena accessible and appealing to JRPG fans who loved Persona, but may not have played many fighters before." 94/100
