Nobody cares about a female MC in non sexual games. I think the point is being missed here. The problem with games with a female MC is not even about the female MC, but what a female MC generally implies about the game itself. There are some great games on here with a FMC that do a great job of showing the female perspective (Crimson Grey 1.5 is a good example).
The problem is that the vast majority of female protagonist games are not about exploring a female character in an interesting way, but rather the game is simply a mirror of many male protagonist games in which you go out, look for, and engage in sex. In a MMC game, it is a game where you go and bang chicks. In a FMC (non-lesbian) game, it is a game where you go out and suck cocks and get banged by dudes.
Games are enjoyable because in them you do something you want, something you fantasize about. In Minecraft, you explore an interesting world, gather resources, and create structures (good times). You can play as a MMC or FMC in that game and it's the same experience. In MMC sex games and FMC lesbian games you chase women, create relationships and have all kinds of sex with beautiful women (awesome!). It's nice to be male, but female lesbian is great too. However, in most FMC games, you go around sucking dicks and getting gangbanged by dudes (fucking gross). Unless you are a homosexual (or bi but don't want to admit it to yourself) or a strait woman, you are not going to enjoy a game about sucking cocks. THAT is why so many of us are immediately turned off when we see the female protagonist tag. Being a female is not the problem. Playing a game about getting banged by dudes is.
