If this project has a website? Maybe there is some kind of press release of the project or other documentation?
I think that there is no website since the development of the project has not yet begun and there is not even a strategy for creating and developing the project yet. In fact, having just an idea is not enough to make a successful project.
I agree with you, the idea is not enough, some kind of plan and strategy for further development is needed. I already know several decentralized games in which it would be possible to use the idea that STONE offers, so I see a perspective in this project.
I also know several such games and I would like to see something similar to the STONE platform implemented in these games. But I have no idea how it should look and how easy it will be to exchange tokens.
