Pokéngine is different from other monster MMORPGs due to its heavy focus on user-created content. With the exception of the Nintendo dex, Retro Kanto and Neo regions, all Dexes and regions available on-site consist of user-created fakemon, maps, and events. Because of this, Pokéngine's new content is entirely user-driven. Anyone can apply for a Dex or a Region, but only projects that show a strong commitment and high level of quality will be approved.
