Persona 4 Arena was one of the rare cases of a PS3 game being region-locked. If I recall correctly, according to Atlus USA, their corporates in Japan issued the region-lock because they feared that they would lose profits from Japanese gamers (I think their biggest market) importing the cheaper US copies. I remember some controversy at the time with people fearing that this would lead to more Sony titles becoming region-locked.
