redo the math for an indie with Unity Personal and a sudden hit with 250k sales

    Units Sold:   250000
    Gross Sales:  $1 247 500

    Steam Fees:
    $0-10M (30%): $374 250

    Unity Fees (personal or plus):
    250 000    :  $50 000

    Net Sales:   823 250

Now it's more or less 6%, and that's before development costs and taxes.

It's a big bite for something that's impossible to code out of the project.

Imagine if Oracle charged a dollar every time someone ran your software the first time on the JRE in that machine. installation on a new machine? pay again. Old customer reinstalls the JRE? pay again. main executable or JRE update? pay again.

Not so funny anymore.
