Unity License Fee will change on 1-1-24.
https://unity.com/pricing-updates
It will be retroactively applied on all installs of a game.
The developer will incur a fee for every install of their game.
Unity say "we are introducing a unity runtime fee that is based upon each time a
qualifying game is downloaded by an end user."
so every time you install a game built in unity, the developer would be required to pay a fee.
(this has just been announced 12 Sep 23, many are expecting some sort of retraction or lesser outrageous costing by 1-1-24)
How will this affect TSO and its playerbase ?
could potentially be very bad for TSO.
[EDIT]
according to the link above :
Question : Does the Unity Runtime Fee apply to web and streaming games?
Answer : We are not going to count web and streaming games toward your install count.
Hmm so TSO is safe then it seems - at the moment..
