Some developers are seriously considering de-listing their games from online shops when the Unity Runtime Fee kicks off at the start of next year, meaning some titles built on Unity could end up being temporarily — or permanently — unavailable. Here's what developers are saying about the Unity Runtime Fee on social media, and what games could be impacted.
There’s nothing implicit about “opening the project in unity” that needs to be a trigger for terms to change.
If you make and distribute a game made in unity, then you are distributing some unity IP. You would need the license holder to grant you permission to do that. The terms you agree to with unity are what grant you the right to distribute this.
So this has very little to do with “have you opened the editor lately”, and is more similar to when e.g. Dead By Daylight has to stop selling a dlc character because they don’t renew an agreement with the rights holders.
That’s because digital media licensing is a whole circus. We aren’t talking of using someone else’s likeness or characters. What if Microsoft Office decides that they will charge retroactively about every file previously created with those tools regardless of what compensation they may already have agreed to and received? Does that seem even remotely reasonable in the least?
Do publishing houses need to pay leases to printer manufacturers per page printed on top of their own material costs? Do they need to pay every time a new reader opens the book the first time?
It’s not reasonable to just go “the company said so, therefore this is how it has to work”, that’s just being a chump.
