Kotaku has the surprising news that id Software has been acquired by ZeniMax, the parent company of Bethesda Softworks (thanks nin). They have interview quotes from id CEO Todd Hollenshead and ZeniMax CEO Robert Altman indicating that this will not change any of the core principles of either company, nor will it impact publishing arrangements already in place for future id projects, though word is ZeniMax is now the publisher of id's upcoming DOOM game. "We're really getting kind of tired competing with our own publishers in terms of how our titles will be featured," says id Technical Director John Carmack. "And we've really gotten more IPs than we've been able to take advantage of. And working with other companies hasn't been working out as spectacularly as it could. So the idea of actually becoming a publisher and merging Bethesda and ZeniMax on there [is ideal.] It would be hard to imagine a more complementary relationship. They are triple A, top-of-the-line in what they do in the RPGs. And they have no overlap with all the things we do in the FPSes."
