Grimdark? That's not the way I remember it.

They moved away with procedural generation when they worked on the creation kit first released with Morrowind, which has gotten a lot of use since then: Oblivion, Skyrim, Fallout 3, Fallout New Vegas, Fallout 4. So, uhm, I don't think it had gone that bad for BGS just because it's latest release is a flawed update of the engine.

Daggerfall is a fun slog where everything is pseudo procedurally generated and the boredom aspect comes when you become aware of the general repetitiveness of the engine, but it is very grindable because it is essentially all radiant quests and because it has very dynamic systems - which also work out to very exploitable systems to easily reach godlike power with little effort. Because you don't have to listen to exposition and can just go nuts on the gameplay, it's very replayable. Unfortunately, they seem to want to go back to the Daggerfall procedural generation system without really having the engine, which was designed to move away from that, configured for it, and it's going to be much harder.
