Horizon will probably have a better and more interesting combat and story, but this is the first 3D Zelda that I've been looking forward to in more than a decade. It will probably also have dungeons which will deliver more diverse and well crafted level design and puzzles that can't be done in an open world environment. Though I'm concerned about the expansive empty spaces in Zelda. They had a thematic purpose in The Shadow of the Colossus, but I'm not sure what they're doing here. I'm equally concerned about how the story will be handled in Horizon and how interesting will Alloy and other characters will be.
Even though they appear have some similarities, they're still very different games, and I want both.
I honestly just commented here to tag this thread and read all the boiled piss.
