Love it.
I always get the feeling that people asking for BB2 just want more of the same, which tbh I find unnecessary as Yharnam is already perfect. BB is my favourite game ever but If that's the case I'd rather have Fromsoft working on new worlds and IP.
On the other hand, I'd love a BB2 with a huge shift in setting like the one proposed here or maybe one that takes place in the sea with pirates and what not.
BB2 taking place in Loran with open-world desert areas also makes sense considering how they are already getting some of that experience from working on ER.
