I'm a dude, and I always play female characters if given the choice, so naturally that's what I did in this game, too. Starfleet character is an Andorian, and KDF is a random alien. Starfleet bridge crew is all-female as well, mostly Andorian, while KDF is mixed because Gorn and Nausicans are what I keep getting.
Never been hit on in this game, or any. Of course, I tend to stay away from the public chat, so I wouldn't notice it if it ever happened. And I think my 7-ft rail-thin Oompa Loompa lady would stand out in the Klingon Academy.
