Can this really be considered a gameplay teaser?
You can just see Link riding his horse through a wide, beautifully animated world.
In this sense I don't understand all the people speculating and complaining about a lack of gameplay possibilities and mechanics, storytelling etc.
We basically haven't seen anything (except landscape, which is acutally filled with interesting buildings, take a closer look), so we don't know a fuck about this game.
We should stay calm until it is fully revealed.
