The Minecraft Star Wars Prequel skin pack adds a number of new character skins to Mojang’s wildly popular sandbox game, including key characters like Anakin Skywalker, Obi-Wan Kenobi, Padme Amidala, Darth Maul, Mace Windu, and Count Dooku, among others.
This follows Minecraft skins featuring characters from Eps IV-VI.
