But, a very good idea no less.
Here's the thing though, when archvile revives dead corpse on doom, they are already to shreds and are brought back brand spanking *smack* mmm, mmm, good, new so there's hardly any degration taking place...And there is this doomRL where anything can jump off traditions.
The others have no problems with the insane difficulty of Nightmare, but even so the idea sounds like a good add-on to the strategy element, where you have to deside what to bring with you when going down farther in Hell on Nightmare. This does, however hampers the core of what made nightmare, a nightmare.
I'm so-so with the idea, but it does add strategy to gameplay. Do you have any idea that can make this work some kind of way and still keep it nightmare?
