ZA\UM splitting into 4 separate studios is the only thing I need to instantly understand that neither of them will ever produce a spiritual successor to Disco Elysium.
I'm not saying a spiritual successor is impossible, per se, I'm just saying that it won't come from any of the four studios.
DE is not just Kurvitz or anyone else who worked on the game in particular, it was a combination of *all* of ZA\UM, the effort of everybody to produce a game like that.
So if you take all that talent, and divide it by four, with no particular balance of talent guaranteed in between, when, I'm 80% confident to call it, none of them have what it takes to make a worthy heir to DE's fame.
