Where we disagree is you see NFT as the work, whereas I see the game as the work and NFT to be part of that work.
If credits are given in the game's credit, then it means there were credits given. In a royalty-free license, payment for the license is the compensation.
And anything would be interpreted in a myriad ways as long as it doesn't go to a court, where which interpretation is correct is decided.
As I said many times, I haven't played the game and can't comment on if there were any credits in the game.
I don't agree. But if you want to put it that way, they are not credited.
. . .
If they are not credited in any way, then it is a breach of license for some of the 3D models. At least for the ones where such a clause exists.
