> Duping though is not a practical concern. NFT contracts have stood the test of public interest and time. A large number of contracts have had multi-million-dollar vulnerabilities. Even one vulnerability in a cross-game-item contract would affect not just the game where the item was created, but literally every single "connected" game. Those in-game-economies would all die simultaneously, and players would abandon en masse. Bartle's point is valid; this is not something you just issue a patch for in a game. It is a fundamental catastrophic flaw with trying to transfer objects from one virtual world to another, blockchain or no.
