I have seen a similar type of game, called : Augmentors that was sponsored by one of the investors in the series - Shark Tank on TV. The site is augmentorsgame.com and it is still active after all of these years, but I do not know if it is successful or not. (founded in 2016)

I did not buy any of the tokens back in the day, because there were many of these "token" based doing the rounds and I thought it would just be one of those fly-by-night projects.

Good luck with your project... I will check in to see how you progress.
