I'm not trans at all, but sometimes I choose to play as a girl just to make real men mad, such as in laser tag (that's a very obscure TheOdd1sOut reference). The fact that I can't do that in Pokémon Red, Green (the Japan exclusive one), Blue, Yellow, Gold or Silver is kinda silly.
I usually choose to play as the girl because devs typically make girl characters have much better customization options or just character designs. Not always but has been a trend i noticed a long time ago.
Like choosing outfits or hairstyles.
Theres usually a lot more options to choose from and also your choices usually are more noticeable when you use your character in game.
Im happy that devs seem to like to give lots of beard styles now so that helps me find more options that i like for male characters
I wish all the options were just available to whatever body type you choose instead of being restricted.
Also, forgot to say theres almost never make up choices for male characters. By choosing the female character/bodytype, especially in less fancy games, the way a characters face looks is usually a lot easier to finesse if you dont like the default options you get. And im refering to just basic bone structure/sallowness of face.
A lot of preset male charactures just look lifeless or hungover
