@unity What about free to plays with only a small portion of paying users ? if you have a 100k new users per month that don't pay anything but you're still eligible for the fee based on past revenues and installs, then you're charged despite not making any money ?
@unity The fee not being related to the game's price is a weird decision : for games sold at $1 the fee will be quite hefty, and for games sold at $200 the fee isn't very significant.
