Riviera is a turn-based RPG title. The game consists of some strategy and dating sim elements, pretty much like all Atlus titles. One of the unique characteristics of Riviera is the conversation concept. Sure, every game has characters talking in them but with Riviera the conversations actually mean something.
Players will take role of Ein and whenever you are talking with another of the main characters it will affect the outcome of the game as well as their level of trust in you. Players will often have two options to choose from when engaged in conversation so choose carefully.
