I have just started a new campaign with three new players. One has some experience in DnD 5e. One is new to 5e, learning through playing Balder's Gate. The third has no RPG experience at all. They have all said they have interest in The Lord of the Rings, at least through movies more so than books.
My problem is that they cannot seen to grasp the ideal of heroes in Tolkien's world. They keep leaning toward being shady and greedy, even though I have explained money is not a driving force in this game. And the newbie player doesn't recognize a difference between pipe-weed and pot and seems to be turning his character into an addict. I have explained about shadow point accumulation and the consequences. I have explained about the case that there can be no "evil" player characters. They do not seem to be greatly concerned.
In standard DnD, as a DM I would just adjust the campaign to accommodate amoral or even evil PCs. This cannot work in LotRR. Advice?
