@Fandyllic yes... the Druedain are certainly very mysterious and unique. They seem to be some kind of Neanderthal or Native American type of culture. One also wonders if they're related to Hobbits. Perhaps they stem from the same Proto-Group.
Even so, none of you have to listen to me if you don't want. I'm not saying all people are entirely bad, I'm just stating it as a fact of human nature.
My favorites are definitely the Gondorians because of their architecture and government, Numenor because of its history and religion compared to the rest of the Men, and the Easterlings because they look so mysterious, yet mystifying at the same time. Also because I like their fashion
Rohirrim. They come from the same ancestors as the Edain / Numenoreans, but just never went westwards. I feel like there should have been more credit and attention to them.
