This is extreme conspiracy from what I gathered, take it whatever you want. In July 2015, CIG formed Frankfurt studio, and then just one month after, in august 2015 id software Frankfurt was also formed. Why is this relevance? Because Bethesda was making starfield, which also trademarked in 2013, just right after the huge success of SC campaign in 2012... Zenimax, the parent company of both Bethesda and id software, has history of trying to acquired other studios by shady tactics, Arkane Studios, Human Head... are one of their victims. They needed high profile engine developers that was fleeing away from Crytek's sinking ship but CIG seems to be always one step ahead of them. Zenimax also used Skadden to sue Facebook too...
