@DavyGreenwind I know you're just using them as examples, but considering how many products out there, specifically Fantasy RPGs of all kinds (TTRPG, MMORPG, CRPG, JRPG, etc) use the base DnD classes in a way similar to WotC's definition (not to mention the race names, the ability scores, etc) how would this affect things, if at all, outside the TTRPG space. If such things ARE copyrightable, then wouldn't that put a huge target on the backs of any RPG game maker that makes or has made similar systems, even if it's not TTRPG?
I would be interested to see reasoning as to why Charisma, which is defined in the dictionary as "compelling attractiveness or charm that can inspire devotion in others." would be copyrightable as a mechanic involving the ability to charm or inspire someone. At that point, wouldn't it be copyrighting the natural assumption of what that word means in the context of a game?
