Final Fantasy Origins v. FF I&II: Dawn of Souls
Well FF Origins retains the high difficulty of the original games, while FF Dawn of Souls make the game (well, ridiculously) easy. The level cap is raised to 99 and you level up insanely quick, and the monsters are for the most part a pushover. Nevertheless, I liked Dawn of Souls better because it was an ideal game for a handheld, while Origins is a bit more "hardcore." I hope this helps.
