Epic allows devs to stay under the license terms for specific versions of the engine. If they started charging for installs, devs can just use the older engine versions and avoid the charges.
They “don’t” allow it, that’s how licenses work.
I keep seeing comments like these on source available nonfree software, but it really doesn’t factor in the fact that older software is NOT going to be used due to bugs, features missing, technical debt, secuity vulnerabilities, etc. So unless it is forked (i.e: OpenTofu), it is as good as useless for everyone but hobbyists.
It’s allowed by a specific clause in their TOS which assigns a EULA version dependent on the engine version. The EULA itself is different for different versions.
The point is that devs choosing to stay on an old version would not be good for Epic, so they are unlikely to directly create the circumstances where that is the logical result.
Unity also had that clause
In fact, they tried to delete it after their announcement
Yup, they actually removed the entire GitHub repo that they made specifically to track those changes for transparency.
The clause is:
My understanding is this is fundamentally different to the Unity clause you’re pointing out.
Another thing is that Unreal is
open sourcesource accessible. If there’s a bug in 5.0 that is resolved in 5.1 but you don’t want to accept the amended terms for 5.1, it’s possible to fix the bug and build the engine yourself. In the event of a significant change like the one with Unity, I imagine some dev group would just fork it and maintain it themselves.They do, though. Not only do they offer multiple, flexible licenses, their basic license specifically guarantees that it is irrevocable. In fact, if that basic license isn’t good enough, they are open to license negotiation.
I strongly recommend reading their basic license. It’s already one of the most fair and reasonable “out of the box” licenses in the industry.
