Crystal Dynamics who created games for the Tomb Raider series between 2004 and 2016 now own that series, despite the fact it was originally published by Eidos back in the day. Eidos Montreal has taken control of stealthy immersive sim franchises like Deus Ex and Thief, however, so they’re probably busy with other things anyway.
These intellectual property rights transfers are occurring because Crystal Dynamics, Eidos Montreal and Square Enix Montreal “amongst other assets” are being acquired by the Embracer Group for $300 million. It has previously been announced that the acquisition process is expected to be complete by the end of September.
It is still unknown what Square Enix Montreal will be called now that it is no longer a part of Square Enix.
