Back in the day the 10hr+ youtube tutorial series was considered prime viewing before even playing dorf fort, for someone without any traditional rogue experience. Even watching a condensed video and starting, I don't imagine the game would feel accessible for many hours for the average AAA enjoyer. My 6yr old however, is able to pick up and finish most any appropriately age rated AAA game. 5 minutes of experimenting with the controls and they are as good to go.
