Pokémon Sweet and Pokémon Sour are the first two main series Pokémon titles in Generation Dream, developed by Game Freak in cooperation with Blender Maximum. The two games are both role-playing games as with past titles, and, as with previous generations of Pokémon, introduce new Pokémon into the series.
Pokémon Sweet and Pokémon Sour play similarly to past games in the series.
The player character will choose one of three starter Pokémon, battle and catch others in certain places, and duel with non-playable characters and other players. Each Pokémon has its own typing as well as moves that they can learn by gaining experience, leveling up, or through teaching them. A Pokémon's type will determine which Pokémon they are more effective against, and a Pokémon will have additional power when using a move of its own type. In addition, two new types are added into this game. These types are called Heart and Science.
