So, I'm wrong because it might be possible to play DnD in Middle Earth... even though to my knowledge there is not a single officially supported setting for Middle Earth in DnD?
Tell me, how many of the most LoTR products for gaming have focused on hobbits as main characters? The last big thing I remember hearing on the video game front was... Shadows of Mordor? And, I never played it, but the main character and every single scene I ever saw on every advertisment never featured a single hobbit. It might be, and I know I must be incredibly arrogant for even considering this, that maybe Hobbits didn't fit the game they were making.
So, yeah, the books written had a specific role for hobbits. That role does not translate well into DnD. It simply doesn't, and instead of trying to prove that it somehow does, you resort to calling me names.
