Heroes V - Remake "File restructuring, 'junk' cleanup, and game optimization"

I had a similar experience. The person responsible for these inquiries forwarded my letter to two employees in charge of this matter, and then one of them gave a POSITIVE response, stating that for non-commercial projects within the framework of their game series, it is permissible to use content from these games!

Sometime ago I tried to contact Nival and Ubisoft to request the use of H5 source code for non-commercial use.

Nival said that their hands are tight without permission from Ubisoft.
Ubisoft did not respond to my e-mail.
