In the context of fictional universes like those in Doom and Wolfenstein, the ownership typically lies with the intellectual property (IP) holders, which are the companies or individuals who have created and legally own the rights to those universes.
the Doom series is owned by id Software, a subsidiary of ZeniMax Media (now known as Bethesda Softworks), which in turn is owned by Microsoft. The Wolfenstein series is owned by Bethesda Softworks as well, with development primarily handled by MachineGames, a subsidiary of ZeniMax Media.
However, it's worth noting that the gaming industry is subject to changes in ownership and acquisitions. Therefore, it's always a good idea to verify the latest information from official sources or news outlets to ensure accurate and up-to-date information on the ownership of specific intellectual properties.
