Code Club AB Code Club AB Code Club AB is a Swedish video game developer based in Motala, founded in 2007 by Rolf Jansson and Markus Persson. The company developed the sandbox massively multiplayer online role-playing game "Wurm Online" and its standalone version, "Wurm Unlimited". Code Club AB was founded as Mojang Specifications AB by Rolf Jansson and Markus Persson in 2007, as the game started to turn a profit. Later in 2007, Markus Persson stepped out of the project and left the company, however, he wished to retain the "Mojang" name for himself, because of which Jansson renamed the company Onetoofree AB.
Mojang initiative started in October 2011, "Mina Kvarter" (My Block), which gave young people in Swedish communities a tool to visualize how they wanted to change their part of town. According to Manneh, the project was a helpful way to visualize urban planning ideas without necessarily having a training in architecture. By 2016, 300 of the areas UN-Habitat plans to remodel will be recreated in "Minecraft". ZeniMax Media, the parent company of Bethesda Softworks, filed a lawsuit against Mojang on 27 September 2011, claiming that Mojang's planned trademark of the title, "Scrolls", infringed upon Bethesda's trademark of "The Elder Scrolls" series.
