This is not something new though. I remember many gaming based tokens that were launched in the mid-2017 crypto hype aka ICO craze. One such name that I can recall is Nitro

Project had campaigns in this forum too. Did it take off? I dont think so, their roadmap is still last on 2019 which is 2years ago. Social media channels are inactive and I am sure it has become an abandonware after its lead advisors have sold off their bags. This is very common in this sector.
The concept of playing games to earn tokens, using tokens to buy stuff seems very good but never worked out in the past. Every few days a new project with the similar idea comes up but never becomes anything big.
