It looks more like SMT:Nocturne/Lucifer's Call than any of those games. The battles are in 1st person with 2d characters like in SJ,but it's not a dungeon crawler. --- The official Azrael of the Shin Megami Tensei IV board.
Storyline wise it seems like it will be a throw back to SMT1 and SMT2. Gameplay wise you could say it's a combination of Nocturne, SJ, and Devil Survivor. Their third person dungeon crawling like in Nocturne. You fight in first person battles like in SJ and Devil Survivor. And yes SMT4 will be stand alone title, but most likely there will be a few references to the previous main titles. --- "When you come at the king you best not miss"
