GB- Pokemon Blue

Pokémon Red and Blue are played in a third-person view, overhead perspective and consist of three basic screens: an overworld, in which the player navigates the main character; a side-view battle screen; and a menu interface, in which the player configures his or her Pokémon, items, or gameplay settings.

The player can use his or her Pokémon to battle other Pokémon. When the player encounters a wild Pokémon or is challenged by a trainer, the screen switches to a turn-based battle screen that displays the engaged Pokémon.
