MIND≒0 (here's the teaser site), new Vita game announced by Acquire, has a few similarities to the modern Persona series. This Japanese blog, for example, is saying it's a Persona 3 ripoff. Because of this, I feel compelled to make a list of similarities between Mind 0 and Persona 3.
|Mind 0||Persona 3|
|JRPG (turn-based battles)||JRPG (turn-based battles)|
|High school setting||High school setting|
|Set in modern day Japan (Akihabara, Yokohama, Amamiya, and Nippori...)||Set in modern day Japan (fictional locations)|
|Two worlds (real and spiritual)||Two worlds (real and Tartarus)|
|Characters use the power of MIND (Mental Inside Nobody Doll) in the spiritual world that summons an otherworldly being from one's soul to battle.||Characters use the power of Persona in Tartarus that summons an otherworldly being from one's soul to battle.|
|2D adventure game-like conversation scenes.*||Social Links.*|
|Character portraits (in battle and in dialogue)||Character portraits (in battle and in dialogue)|
*Currently nebulous similarity.
I'll update this as more info comes along.
