I remember it because I basically asked what happens when you play an alien character from a species with three sexes and it* was of the sex that didn't map to male or female. Mostly because I thought the whole point of the game was for the newcomers to band together and kick both sides'** asses.

(The answer was: 'dammit, newbie just pick one', except probably polite. But there was to be none of this non-binary biology present.)

* Canonical pronoun, not trying to be offensive.
** There was some kind of hyper-macho side the Amazons were fighting against or something.
