The partners listed are eth and polygon. I don't think you can consider them as partner if they will be building their platform under these networks. It is more of, they will be deploying their project on these networks. And I think SSG is their partner to build this gaming network. They need to have something to offer before launching their IDO. Otherwise, it would be hard for them to raise money if the investors are not seeing any tangible developments with their project.
