Your goal is to become a Pokemon master by defeating the gym leaders of the 8 cities in your region. Map is randomly generated, deploy your pokemon using "R" and a direction to fight wild pokemon and gain XP (or to weaken and catch them!) your pokemon will evolve and learn new skills.
Pokemon data is heavily based on the Gen 1 official dataset which I've been gathering from around the net. This is an open source project: https://github.com/slashman/pokemonrl contributions are welcome and you are also welcome to use the data in your own game.
