Dwilight and BM shouldnt be a kids game, its a low-fantasy hardcore political simulator and if you cannot seperate your distaste for 'drugs' or violence or poltical intrigue from real life it is you who have the problem with roleplay in BM anf the ability to immerse your character in the liquids of autonomy and creation.
I don't think he's suggesting that the CoB should be disallowed because of the drug theme. I think he's suggesting that that theme will simply turn a lot of people off from it. And I think he's right—but I also agree with you, that this is some of the kind of thing that should absolutely
exist in BattleMaster.
Just don't ever expect it to become the norm
