Im a Dm and I was looking through the Core Rulebook when I decided to change the races that I allow my players to select, I started by eliminating the Half Races, Half Orc/Elf, no one plays them and I never liked the mix race thing, to compensate I replaced Half-Orc with Full Orc due to players generally preffering to just go Full anyway, I added Aasimar and Tiefling to the list since they're always interesting and not to powerful to run in a game, that leaves me at 8 races for my players, but I was thinking of making it an even Ten, my first choices are Replace Half-Elf with Tengu for a more exotic flair and then maybe a Home-Brew Dragon Born style Race, Any Suggestions?
I'd go with something a little unusual, like a bariaur or mini-sphinx or raptoran something.
But ask your players what kind of races they want to play. Maybe they want to play something you didn't even think of, but would really like to use.
