So the production for DS2 was quite troubled. The way I remember it was that Tanimura and Shibuya were in charge of it while Miyazaki was busy with Bloodborne. About halfway through the process the higher-ups decided it was shit and booted Shibuya off, leaving Tanimura in sole charge. The narrative was remade from scratch, characters were revised or redone and existing assets including areas were stitched together best they could to slot into the new game. In its own way it’s an impressive feat, but you can understand why it’s messier than DS1.

I have no idea for DS3 though, apart from that it had a pretty short development cycle, so I’m assuming sacrifices had to be made. Many of the levels themselves are great in DS3, but on the macro level it’s much more linear than DS1 (DS3 is almost just a long corridor). It could also have to do with a shifting of the focus from exploration to tough boss battles.
