You must play very few games as there's only a handfull that give you the option to play as a female.
It's also quite funny that the gender of the protagonist is the main 'selling point' for you. I realize it's an RPG and you may want to RP as a woman or whatever but there's so much more to the game than your gender.
I never understand the whole "generic white male" stigma some gamers(seems to be the modern feminist crowd of gamers) have. How is a white male generic and any less interesting than if the character was black? Or female? Does having a hero be black automatically make them interesting? Same goes for female, how is a GENERIC WHITE FEMALE any more interesting than a male counterpart? To me, they're all the same. It's how you develop the character that makes them interesting. In games like these, the protagonists are fairly blank slates for you to shape into the type of character you want them to be. For example, I found the good guy path in DA2 to be a tad boring, while the Humorous route was actually really entertaining and witty.
I don't know what you would consider "very few" games, I have ended up with several games that are "meh" (and yes, these are usually the games with a fixed male protagonist though usually I buy these cheap and used when there's nothing better out) but the ones I do end up loving I replay many times and end up putting hundreds of hours into, buying all DLCs for them, and instantly buying any sequel. I used to play JRPGs almost exclusively and there's a higher percentage of JRPGs with female protagonists but it's still skewed and only recently have more games allowed you to play as female. Growing up I was usually stuck as male, and honestly I'm sick to death of it. Movies, music, tv shows, books, etc...all have an even mix of genders portrayed and those industries haven't collapsed yet video games lag far behind.
As for a person's gender or race automatically making them interesting, it doesn't. However when a company uses that same focus test muscular straight white male with dark hair and stubble or beard that has literally been used THOUSANDS of times, I think well, they have zero creativity with the lead character design, they probably have zero creativity with his personality (one dimensional "let's kill these bitches!") and its most likely about combat or a certain mechanic and story, characters, roleplay, etc...are either pushed to the side or non existent as almost every one of its' clone army has been. The focus test white guy has become the generic because he's everywhere. Just having a female or someone of another race on the cover would already signal "not generic" because they are hardly ever used.
I wonder if you'd feel it was so unimportant if YOU were forced to play a set Asian female with blonde hair and a bob haircut with the same bland non-personality in almost EVERY single game for your entire life and those games involved little to none of the things you liked and hours of bedazzling high heeled shoes? And even the ones where you could play something else or weren't about shoe sparkles never mentioned it but instead shoved default lady in your face and made you think it was just more of the same.
