The default runner is a man. It is free (and the game is free as well)
But take a look at upgrades that require to collect or buy coins (either way you expend effort or money as per freemium model). So if you want to choose a female runner you have to first collect 5000 coins (by running the man) or pay for it.
I see this as bad price discrimination – purely s a pricing practitioner as well as a dad. But …
My eight year old daughter, who has become a fan of the game, believes it isn’t so. She argues it merely says you have to pay more to be a girl because girls are superior.
What is your take?

Interesting point. The next avatar is of African descent and then the one after that is Asian. Is Caucasian the commodity? 😀
