It was on the PS2, and that's a good eye, because it was also made by the people who made the Persona series (Atlus). It was my favorite RPG because of how dark and creepy it felt. It takes place in post-apocalyptic Japan and you and your friends basically become prophets for their own gods and end up fighting each other to determine which person is the new "god." Your character is a little bit of everything and of course wins in the end, when you beat lucifer. It's an interesting game and I loved the art style, characters and music! It makes me smile to know someone works out or does any art to my music :) cheers @tetsuo !
