I think a lot of people associate human only parties with human only(or human mostly) real world settings, like Rome or Carthage. My personal experience is that most players don't want to do that much realism, but do like X race only campaigns once in a while to switch things up. Switching things up once in a while adds to the fun, which is what the game is about. That it removes some options for one campaign is irrelevant. Fun is fun.It's interesting that some folks are making connections between "humans only" and realism, grittiness or low fantasy. That's the Game of Thrones influence, I guess, but it never really occurred to me. Both Arthurian fantasy and pulp fantasy lean toward humans only but both also support the kind of cinematic and high wonder fantasy 5E is good at. If I were aiming for low or gritty fantasy, regardless of the presence of playable non-humans, i would definitely go back to 1E or B/X (depending on how crunchy I wanted my game).
My break as a player is coming to a close. I do most of the DMing for my group. The players are brainstorming what kind of campaign they want to play so that I can start prep work while the current campaign winds down. So far among all the other ideas, I've heard human only, drow only and goblin only. The latter two are surprising, because they are actually considering an evil campaign and that's new.
