'We' is very vague when you are responding to my post. I'm sorry for such an error but nevertheless he was technically right because the developers did change the game engine. Unless you're blind and can't see the graphical differences between Oblivion and Skyrim.
Btw they changed the engine. Wanna know how? No more fucking oblivion babyface NPCs.
Fallout 4 will be development by Beth or Obsidian?
