I came in one day, told my players this game sucks and everyone immediately started searching for their own game of choice, never looking back at 5e. we’ve settled on WoD as the game we go to, but we’ve got a Pathfinder and starfinder game going, we’ve played cyberpunk RED, shadowrun, cthulhutech, the witcher rpg, besm, exalted, CoD, wrath & glory, and we’re planning a final fantasy d20 game. It’s down right sad that some people won’t move on from 5e tbh.
Big cats have hunting instincts that are hard to turn off even if they like you (see: any news story of a big cat eating their owner), humans have instincts relating to forming communities. every single species has some instincts they follow and they aren’t the same as ours, they’ll deeply shape how a species’ cultures/morals/etc develop. Just saying goblins are little green humans is deeply boring and hurts world building.
