Carmack also tweeted and spoke often about Zenimax refusal to touch VR and support Occulus. He basically said Doom 3 BFG Edition VR support was done by him OFF the clock and he would have to buy HIMSELF from his own money all the copies that went with Occulus KS fulfilment.

Basically Zenimax didnt want to do anything with VR while he was there, but now those slimy lawyer cockroaches want piece of the action.
