I bought a steamdeck recently and I also put Disco Elysium on my watchlist with some temptation to pick it up at this low price. The problem that I have is that I once started playing it when it was part of playstation plus but I didn't get very far (barely past the first screen) as it didn't capture me instantly. I'm quite sure though that I would love it if I really put the time into it properly.

Enjoy your gametime!
