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

Personally, I received consent from Ubisoft representatives to use materials from their other games for developing free mods for this game, and therefore, using content from my mods in this way is not very legal.

Wow, even like that? Respect and kudos!
It's a shame that Ubisoft is probably not interested in "old" Heroes 5 right now, so it's unlikely that modern modders will be able to reach out to them and ask for permission to use content.
By the way, I used material from your mods. As far as I remember, I asked you for permission, right?:confused: :smile41:
