This mode is an overkill.There are numerous types(not exactly types but having almost similer properties just change of name) of resources which makes it less of a fun.I suggest that instead of increasing the type of resources it would be easier if the number was kept small,i don;t mind the smelting and stuff but the number of resources at present in game are simply overkill.Hardcore doesn;t mean working with huge types of resources.I highly suggest metals to be named in tiers and if possible types of clothes too.It makes it simple yet hardcore.
