Hi Hyncharas,
Disclaimer: I am not a lawyer.
There are some clauses in section 4 of the EULA under “However, no royalty is owed on the following forms of revenue:” that read as follows:
6. Revenue from interactive amusement park rides or coin-operated arcade games which use the Licensed Technology; and
7. fees or work-for-hire fees which are non-recoupable for services performed using the Licensed Technology (e.g., an architect-created walkthrough simulation or a contractor-developed in-house training simulator).
These may cover your use cases, but you can also ask at Other licensing options - Unreal Engine to clarify further.
Cheers,
Michael Noland
