I think Online Girls only admit they are girls once they reach a high skill level, this makes it Impossible to judge.
There are some girls out there that a really good, but the very best at RTS and FPS are still guys.
MMORPG's it's pretty split but I think girls are great at organising and communicating.
Girls are great at typing though, a good use of their advanced motor sklls :P
