I am mixed on the "group of weirdos" trope in gaming groups.
In the 80s, we had RuneQuest where you could be a duck or a troll, Palladium Fantasy 1e where you could be a Wolfman, Orc, or Giant, and Tunnels & Trolls had a supplement all about monsters as PCs. I'd argue that PF1e's success was heavily based on that you had many more PC choices than AD&D.
However, the "humans are boring" issue usually happens due to humans being sub-optimal as a race choice in that edition.
