Tbh, my #1 and #2 are basically interchangeable, as are my #3 and my #4, as I love them pretty much the same, so I guess you could consider them tied.
Bonus:
First and most important: MUCH more enemy variety. As good as BOTW is, that was a big let down for me. I expect and hope BOTW2 to fix that.
Second to that, I honesty just expect it to be have the same or similar quality - which is to say, I expect it to be a great game.
Something I'd like, but dont really expect is a more elaborate combat system and an entirely different weapon durability and item storage systems. Those would be much appreciated.
