Digital Devil Saga: Avatar Tuner

 (a.k.a Shin Megami Tensei: Digital Devil Saga) is a spin-off of the Megami Tensei series. Because it uses the same engine as Shin Megami Tensei III: Nocturne, many of its files are compatible between both games, but despite that, its gameplay contains changes such as: having only story relevant party members, combo skills, the Mantra system, being able to freely customize the party's skillsets at any time outside of battle and no demon negotiation or fusion.
