There might be none as well, this is a new field. The problem with your first suggestion is that you do an awful lot of work to map another games NFTs to your own items but presumably get none of the money from them. You also have an immediate balancing problem. And the better way is to just make a game that those players want to play, which is how game populations move around now anyway. The only way I can see supporting external NFTs as worthwhile for a game developer is if they’re already table stakes for taking part. Or say you support BAYC, all that work to address 10k potential users?
