Skyrim on Id Tech 5 would be “completely unacceptable”

Id co-founder John Carmack explains that his firm’s new engine is ill-suited to open worlds: “The megatexture direction [in Id Tech 5] has some big wins, but it’s also fairly restrictive on certain types of games. It would be a completely unacceptable engine to do Skyrim in, where you’ve got the whole world, walking across these huge areas.”
