> nftgamingportal.com could exist which accepts these NFTs (in addition to many others) despite whatever restrictions Ubisoft decides to impose
Ubisoft's coin is on a public chain right now, and they have restrictions that prevent people from using arbitrary 3rd-party marketplaces to trade the NFTs. So it's a nice theory, but it doesn't seem to be working in practice; being on a public chain isn't currently preventing Ubisoft from restricting other portals.
I think people believed this portability was inherent to how NFTs work, that of course anything on a public chain would have to allow 3rd-party marketplaces. But I don't see what mechanisms actually exist to force that outcome; I think that's just a hope that people had rather than an inherent technological property of how blockchain contracts work.
Not really hope, but this is one of the biggest value propositions. If your NFTs give more rights/power to the owner they are going to be more attractive and thus more valuable.
On the other hand being able to have more restrictive tokens enables smart contracts to comply with regulations. But for gaming NFTs it really destroys any added value/utility which is something i should have expected of Ubisoft.
