Variations of Height in video games / hair color

I'm a pretty short guy. 5'8. I constantly feel like a dwarf when I see someone who's like 6'5. Not for insecurity reasons, but just the fact that I'm 9 inches shorter... is a big difference. 5'10 is the average.

So in video games like Skyrim or Witcher 3... or pretty much every video game, why is it that all the characters are around the same height? It doesn't make any sense at all, and it's just one of those things that we all accept and don't realize.

Isn't that strange? Other than different races in games like MMORPG's, or RPG's, everyone of the same race is the same height... give or take 2 inches. Isn't that strange????

Also another thing... why hasn't there been a main character / protagonist that has blonde hair? It's like almost a conspiracy because the only characters I can think of are Princess Peach or Cloud. That's like... decades old.

Maybe Dragonball Z, only when you go super saiyan though... lol

All the main characters in games now are pretty much the same height as everyone else and have brown or black hair.

Most likely for simplicity and ease of using a template.
Why make a unique set of features besides the face and for the most part we could not really tell each other apart with out having our faces either.

BJ Blaskowitz is blonde.

EDIT: And sometimes ginger. and he had brown hair that one time but never mind that.
