Pretty much anything related to ultrahand and recall for me. Just so fun to do whatever with and the amount of stuff I’ve seen others create is inspiring. I don’t get these being slept on or some trying to downplay these as “not revolutionary” when I can maybe count one or two other games that have ever done anything near as close to this, and neither are within an open world. But then again what can I expect from those who said the same thing about BotW’s being able to literally climb anything and comparing it to the predesignated spots that Assassin’s Creed will tell you it’s ok to.
There are other things too, though. The music for one, how it builds on stuff already in BotW as well as the callbacks to older games, and how it’s all rearranged to create something new that still fits the tone and atmosphere. The piano was a great fit for the often solitary journey in BotW, and now adding things like the ehru does wonders to add to the mystery as well as the more grandiose setting, among many other elements.
I like that there are better side quests this time around, often even more hidden behind others as well. Not every one is a winner, but there are a lot that are far more involved and I like that many of the characters are recurring. That’s another thing I enjoyed as well, seeing what they do with some NPCs who might have been relatively unimportant before getting bigger roles now. I’m just worried one of my favorites may not be in anymore…need to go look for her cabin in Hebra but I don’t recall seeing it when I did the Rito stuff.
