Has he ever made any videos of items that he doesn't physically own - games or films? Hell, even that King of the Monsters 2 video doesn't show any footage from games he doesn't own carts of. It's all the same six or seven games.
I mean, yes, he could just use emulated versions or other console ports... but I don't recall him ever using emulation for his game reviews. He may have but I don't remember if he ever did.
