I could be wrong, but I am almost positive that the "SMT" was only added to the western releases, and even then, only added for the third game. There was no "SMT" on Persona" Revelations or Persona 2" Eternal Punishment as far as I recall.JC48573 wrote:Persona is actually a spin off of the SM series, which later became a franchise. They still carry the SM subtitle.
Check out google image searches for japanese ps2 copies of Persona 4. They lack the "SMT" at the top of the cover.
Still, I wouldn't say its incorrect to call Persona a spinoff of SMT, as they do share a lot of siilarities. I just think its more a case of them using what they already knew to make a new franchise, which it appears they had a lot more faith in, since Persona made it out of Japan before any SMT title.
