Shin Megami Tensei If… was a step towards the popular Persona series. Atlus made this Super Famicom game as a what if storyline imagining the events in Shin Megami Tensei never happened. You play as a high school student that enters the demon realm when you find out a fellow student declares himself to be the Demon lord.You get to travel with a human friend in Shin Megami Tensei If… which changes the storyline.
Atlus ported Shin Megami Tensei If… to PsOne and now you can get the role playing game for iOS too. Unfortunately, it’s only in Japanese and has a clunky virtual handlheld interface layered over the game.
You can get the only portable version of Shin Megami Tensei If… for 1,200 yen ($13) on iTunes.
