I love goblins and lizardmen. Goblins because deranged little dudes running around is always a blast. Lizardmen because alligator people with melee weapons are the way I wish dinosaurs evolved instead of being birds.
Kobolds deserved the place in the player’s handbook that dragonborn got. Those little scrappy fuckers maybe being the actual scions of dragons appeals to me in a way that dragonborn just do not.
Pathfinder would like a word. Particularly 2e. Seriously though, the kobolds are great pcs in that system.
