Stylized Anime-Like Graphics
The Persona series has always been beautiful to look at, even back in the days of the original PlayStation. As it moved from PS One to PS2 the visuals only improved. The anime-style it utilizes separates it from other JRPGs, giving the world a great cohesion.
The unique graphical style also means that the game can utilize anime cut scenes and other techniques that you typically don’t see in other games. Because of this the series has a style all its own.
