I've been playing Kentucky Route Zero and it's really something unique and special, but definitely not for everyone (the kind of thing some people will find pretentious and boring). It's like a really slow, dense and uncompromisingly tasteful literary work in point-and-click text-adventure form combined with surreal magical-realism David Lynch vibes. Only a few chapters in, but I think it might be on its way to beating Inside as my favorite example of videogames as art.
Its approach to interactivity is very different from most games in that it isn't really about player agency-- You feel more like a collaborator who tweaks and personalizes a set-in-stone screenplay or acts out a role as it gets performed or something. Sometimes things of this ilk feel like they're just giving themselves an excuse not to have deep video-game-y mechanics, but here it's a strong decision that would otherwise be an unwelcome distraction.
Unless it falls apart in later chapters, it's my pick for best of the year so far (2020 I mean), way ahead of things like Hades and Final Fantasy VII Remake, personally (although I guess that's kind of cheating, since the last chapter is the only new one-- the whole compiled "TV Edition" was released this year, though).
