Carmack left Zenimax because they wanted him to work on sequels instead of VR. They only started caring about VR once the $2B Oculus acquisition was dangled in their faces, and then scrambled to find a way to get a slice that they didn't earn.
I didn't buy DOOM because I didn't support Zenimax's cynical lawsuit/cash grab. Maybe now I'll get DOOM after the Microsoft acquisition closes.
