Bethesda is apparently aiming to be known as the game developer company where you can be involved in lawsuits. Via gamebanshee, Minecraft Creator Mojang AB has received a 15-page letter from the Fallout and Elder Scrolls developer, which alleges that Mojang AB's new game "Scrolls" infringes the copyright of the "Elder Scrolls" property.
Mm. Frivolous much? Somehow I'm getting the impression that the lawyers over at Bethesda are underworked and overpaid.
Bethesda has also been engaged in a legal tug-of-war with Interplay over the development of a potential Fallout MMO.
