It would depend on the popularity of the game in question.
as a singular purchaser, .2 or 20 cents is inconsequential.
A game that has sold 10,000 copies if each player installed
it only 1 extra time. that is a 4,000 dollar check.
The more popular a game is the higher the instant return.
7DTD has sold 16,000,000 copies. If each person installed it
1 extra time, then that is $3,200,000.00 "million" dollars
instant payout.
As an example: i took "4" samples to get a numeric.
Among Us 600,000,000 downloads be generous and say 30 percent
is a secondary install. thats 180,000,000
This is just if a Single extra copy is installed. Its basically
unregulated numeric s.
Among Us: 180,000,000 *.2 = 36,000,000
7DTD: 16,000,000 *.2 = 3,200,000
ape out: approx 200,000 *.2 = 40,000
Rust: 12,400,000 *.2 = 2,480,000
$41,720,000 instant back revenue owed by these game devs.
There are 38 other games. It adds up to, a poor business model
on Unity's part. To compensate, it is to be passed off on the game
developers.
An easier way to look at it is; If you didn't think ahead, got a
woman pregnant, and then expected me to pay the child support just
because i live in the same building.
I hope it all works out
