Which races have you played for a regular campaign? (Don't count anything you played for a one-shot game, or something played for a session or two) This is for all editions of D&D.
My gaming group allowed just about any race in our 2nd Ed. days so my "other" includes a bugbear, a half-ogre, a tabaxi, and a grippli. And I played a halfling in all of the editions I've played.
Human, Elf, Half-Elf and Dwarf for D&D. (At least, I can't recall playing anything else in an actual campaign.) Plenty of other stuff in other games. (Gamma World FTW!)
I have played the majority of races, and am happy with a rich race mixture, but not in the main book. The main book should have about 4 Human, elf, dwarf, Halfling. I also think a lot of other races should be considered human for most cases, like deva, tiefling, dragonborn and such. Make things simpler.
