I accidentally voted for Sekiro, until I realized Death Stranding is a 2019 game (I thought it was a 2020 one, but evidently not). Death Stranding gets my vote: It's not perfect, but it tries to do something different, and I personally liked the game a lot despite its flaws. I can totally get why it's divisive though. Needless to say, other strong contenders for me include Sekiro, and less obviously Total War: Three Kingdoms, which is mainly hurt by its abruptly ended support (it also has its flaws, but it seems to have brought some nice improvements to the series). I haven't played Disco Elysium yet, but it sounds like something I might be able to appreciate a good bit (enough to mention here).
