In theory if some kind of token-as-license system were to be used by a game distributor, it would be trivial to confirm that the token contract address (0xff..) matches the contract address required by the distributor. Other tokens may appear similar, but would have a different addressable hash.

The same is currently true of the NFT art market: an artist can say "I minted 0xff.." and so a token with hash "0xaa.." is clearly not originating from that artist, despite them having some similar attributes.
