The game's development began in 2012, when a group of Pokémon fans from /vp/, a board on the website 4chan dedicated to Pokémon discussion, decided to collaborate on a fangame. Starting in a snow-covered mountain town, a cowboy-styled rival character named Ricardo steals a different, friendly rival's starter Pokémon and challenges the player to a battle. Pokémon Sage takes place in a fictional South American-inspired region called Urobos, with the player being named Simon or Sophia, depending on gender. The Starter Pokémon are the avian Grass-type Foliat, the goat-like Fire-type Kidling, and the reptilian Water-type Aguade.
However, it includes an entirely new Pokédex. Pokémon Sage 's gameplay is standard for the Pokémon series.
