I'm not joking the open world is so big and it's free explore also you can do all the 100s of sidequests in ant order you want and abandone your main quest whenever you want. Also you can even go fight the finale boss in the first half hour of play time (you will die instantly tho lol) there's also so many things you can change in the game by how you play and there's lots of villages to discover and miniboses.
