Does anyone really like the idea of just changing your wall from wood to stone to metal?
To me it seems really cheesy.
It should be damn hard to get off of wood, it shouldn't be just as easy. Nor should you be able to change your wooden wall suddenly into a stone wall.
I do think that upgrading walls is a good idea but it should only add to the progression of that 1 base material type.
Eg - You have wood walls, you use metal fragments to build a frame around the edges, increasing its durability.
It could change the appearance slightly.
Just me?
So are you saying we shouldn't have any stone or metal walls, just wood? Or are you saying that we should have to tear down our wooden walls before replacing them with stone or metal ones, rather than upgrading? Not sure I agree with either...
