I can only comment on my viewings of palying as a female in games. It depends on a few factors, thsoe being is the female version of this race of character look better then the male version or does having teh character be female fit the class that I am playing as if its a game like WoW or Oblivion. A example of this is I play as a Female Dranei Shaman in WoW mainly because I think teh Female Draneis look alot better then the male ones., and thought they looked better in the armor that shamans wear.
Then theres the fact that some RPGs give you a different take on the same things if you play through it again as the opposite sex. For example, when i play Bioware games. I play them first as a Male cahracter, then as a female because im curious how interactions might change in thegame because I am a female that timea round. Situations get a new perspective because of the way other character adress you. I am a dude 24 hours a day 7 days a week 365 days a year and Its interesting to view things as a female in video games because its something I cannot do short of getting a expensive series of operations, and I am comfortable enough in my masculinity to try things as a female and maybe pursue realtionships with the supporting male characters to see the interactions those characters have and see more of the writing and dialouge if its say a Bioware game, because I love the writing in those games and the V.O work. I am not saying I want to be a women, but I am saying thats its a interesting change of perspective if you are playing as a female in a game.
