All discussion I've ever seen about this game on 8/v/ drives me insane because it's obvious most people have never even played it.
<muh walking sim
It's not a fucking walking sim and anybody who says that has obviously only heard about the game through internet posts.
DE's skill system was one of the most unique and innovative things I've ever seen in a game, I hate how a lot of other devs want to "be like Disco Elysium" and rip off its system wholesale without evolving it at all. If you look at the leaked cancelled Disco sequel you can see all the ways the devs were trying to go further, push the boundaries of how thoughts worked and what they could do. Nobody else is doing that.
The game's reactivity is also excellent bar the ending, Gabe Newell once said something like "If a game doesn't respond to what I'm doing it's like a narcissistic injury" and Disco really lives up to that. It has over a million words of dialogue and much of that is alternate lines for dialogue paths. There's a funny moment where you can find racist memorabilia in the trash, but if you decide to take the memorabilia then talk to a racist truck driver, you can show him the thing and ask what he thinks about it. Literally no plot or story significance, just something you can do.
The game is absolutely full of that, things that other studios wouldn't "waste time" on. Every character you meet has a surprising amount of dialogue, and almost none of them are story relevant.
