Bethesda didn't make this game - they licensed it to Zenimax Studios
Yeah I know a studio was created, but Zenimax owns Bethesda, so it's all sort of in the family.
It's a studio that was created for the game basically.. what I meant was I hope they didn't loan/send to many employees over to that division for the game. I know they have a producer/designer who was from the outside but I can't imagine ESO isn't borrowing some devs who could be used for more SP projects.
