Apparently there was a talk at Unreal Fest which hints very heavily at upcoming license changes to non-game uses.
Personally I’m working on a small training simulator as a part of a thesis (in academia) for a commercial for-profit company using Unreal Engine. I’m not too worried about it in general, as I can keep using the older version to finish what I’m doing and it will be covered by the old license.
However, the wording on the EULA raises a few questions:
If we make changes to this Agreement, you are not required to accept the amended Agreement, and this Agreement will continue to govern your use of any Licensed Technology you already have access to.
However, if we make changes to this Agreement, you will not be allowed to access certain Epic services or download the Licensed Technology unless you have accepted the amended Agreement. If we make changes, we will provide you with notice, such as by sending an email or giving you notice when you next log into an Epic service.
My take on it was, when the new engine version is out, i.e 5.4, and it is covered by a new EULA, then only 5.4 onwards is covered by that license. So, for example, I could keep on using 5.3 with the old license and if I had a project with 5.4, that would be covered by the new license.
But the way this reads, is that if I wanted to i.e keep using the launcher, download marketplace assets (even those already purchased), or even download an existing version, I would have to accept to these terms.
In other words, it would be possible that I could only keep using what I have on my computer already and even in the case where I’d have to redownload 5.3, I would then have to accept the new license to continue.
