As much as I am loving Horizon, I dont see what is so appealing about its world. It all feels very samey. Its beautiful, thats for sure but it all has a been there done that type of feel. Its so realistic that its almost boring? I am not too sure how else to put it.
Zelda from what I have played introduces creativity which is fundamentally the main ingredient in encouraging exploration.
This is exactly how I feel about both games. Completed both games, but Zelda has a way more enjoyable world to explore. Doesn't matter what ticks your interest in Zelda...something will be there.
