I am a female gamer. I certainly don't play the "casual" games. I play mostly RPG's, and not JRPGs, either. Yes, I do play the Sims (and 2 and 3), but my favorite game of all time was Baldur's Gate. I also used to play the Gold Box SSI games back in the day. Pool of Radiance, Curse of the Azure Bonds, Secret of the Silver Blades, Pools of Darkness, Dark Queen of Krynn... I also have played Icewind Dale, Civilization (from the Original to 4, and Civilization: Call to Power as well). Older Games like Crystal Quest, Battlezone (from the Arcades) and Tetris were some of my past favorites.
When the game Baldur's Gate 2 came out, and I found out it had romance in it, I was thrilled. But to be honest, the way it was implemented left me completely underwhelmed. For male protagonists, you had three possible love interests: Aerie, the "Good" character, Jaheira, the "Neutral" character, and Viconia DuVir, the Dark Elf "Evil" character. For female protagonists, you had Anomen, and that was it. He started out Lawful Neutral, and could be turned to either Lawful Good (stuffy, arrogant guy), or Neutral Evil (in which case he became an asshat). Spoiled for choice, female characters were, hmm? Okay, there was a UserMod that allowed you to romance one of the Dark Elf male characters later in the game and have him join your party, which also involved something of reforming him, but it shows who the producers of the game thought were more likely to play it.
RPGs also have players who think it is "gay" if a male player wants to play a female character. It's not seen as strange for a female player to play a male character, but in the reverse, you start having other, immature players accuse the player of being "swishy" or even outright gay, which argues to me that a certain subset of players think that anything female is bad or "icky". Women can play men because that's what everyone wants to be (male), but in the reverse means something is wrong with the player.
