Most impressive open world in a game you've played

Skyrim for me. I remember leaving the camp where the game started and heading off to the north to explore and it took my breath away. It was stunning, the world felt absolutely massive and I was hooked on exploring every nook and cranny of it. Mountainous and subarctic environments are among my favourites.

Hmm, sounds like going outdoors in Norway.

I've always imagined that Norway is basically Skyrim.
