I played through KOTOR as a female character, then KOTOR 2 as a female char again. Why?, because there is enough male villains/heroes in SW universe + when I play game that lasts about 30h, I would be rather watching good-looking female than male who looks like a Jesus for an example.
Once decided to try male exile (with jesus-portrait of course ), I came to same conclusion as babydol.
Male exile gets all the fun-stuff: Handmaiden (good for plot-wise, more clues about Kreia's past identity + battle precognition), instead females get annoying and naive jedi-fanboy that doesn't have any importance in plot. And the Atris-exile relationship is far more interesting than archaic and stupid sion-->exile -love, + all those thing that babydol said.
I don't get this: Why does male get all the fun, while female is canon? Did they change female to canon on last second before game was released? Grr!! shame on you Obsidian!
