Not just the year, it is in the top 50 of all time. Beating games like Portal 2, TP, MM, Skyrim, TW3. Also, what has come out this year that hasn't flopped, been a remaster/release, or isn't FFXVI?
but TotK is just GMod with Zelda models and poorly written furry fanfic. Some great elements there, but nothing special, and I'd say it fits in your 'above average open world games'
