Back in 2014 at the Game Awards, the world was shown exclusive off-screen footage of Zelda: Breath Of The Wild (Zelda Wii U as it was known back then). We were also lucky enough to have Mr Miyamoto and Mr Aonuma walk us through it. The video showed many eagerly awaiting fans a glimpse of the world that players would get to enjoy three years on. GameXplain have made a comprehensive video showing the differences between the game we have now to that of the one demoed back then. They do a good job of trying to match up locations by careful analysis of the early map shown on the Wii U GamePad, amongst other things.
