It looks Unreal
Want to take a gander at the most impressive empty room you'll see all day? It's Hyrule's Temple of Time, and technically it's not completely empty. The Spiritual Stones are hanging out where they're supposed to be, and the Master Sword even makes an appearance.
It never fails to be neat watching people use new tech to recreate stuff from classic games. But, if you're impressed by this, think of what Nintendo could do if it took a crack at it.
