I like playing other races, I'll admit. It helps cement the "fantasy" in the fantasy world for me in trying to present an alien psychology credibly during a game. Always humanoid, nothing more exotic than a lizard folk or goblinoid.
The choice of race comes from a desire to play a certain race/class combination -- sometimes a pairing just speaks to me as offering opportunities in play. I have no interest in a half-orc barbarian, but a half-orc paladin or cleric does appeal. I like the thought of a mechanically unoptimized pairing, and then doing what I can to make it work in play, both mechanically and narratively.
