Pixelmon

Pixelmon is a mod created by the Pixelmon Team. The mod adds various Pokémon to the game, inspired from the Pokémon video games. It was discontinued with the downloads retracted after a request from The Pokémon Company. A petition on Change.org for the mod to be restored reached over 9,000 supporters. The mod generated controversy for including DRM  and for issuing a copyright takedown notice against a video news report describing this DRM on the grounds that it showed a small excerpt of the code.
