Pokémon Acanthite is the prequel installment to Pokémon Gold and Silver versions of the Pokémon series of role-playing video games. It is currently in development by a freelance developing studio known as Silver Glance INC. and is the first Pokémon fan-game to receive high regard in its quality and aim at emulating the style executed by Game Freak's developers. The game itself has been in development since 2004, constantly going through design revisions and modifications to its engine. The game has often been delayed due to these issues but is expected to be ready for release sometime in 2009.
The game is set in the fantasy world of Merto, which is the habitat for 275 different species of Pokémon, some of which are exclusive to this region. The game covers the adventure of the rival from Pokémon Gold and Silver who served as the series' antagonist, embarking on a quest to capture and train Pokémon while simultaneously thwarting the movements set by Team Rocket being lead by a new figurehead.
The game is still under heavy development and aims for a release within the next year.
