You know, there's an excellent reason why the PC races aren't all that alien, and why they all play as somewhat exaggerated human stereotypes with cosmetic detailing and stat modifiers...
This is a game played by humans! Your characters must be at least somewhat human, or you're unable to engage meaningfully with them. Sure, Dragonborn are scaly and hulkish, and are born from eggs, but they must be people, or you can't play them meaningfully. (I see this thing all the time with SF, by the way; an alien that's too alien to empathize with is not a character, it's either a plot device or a "bug".)
