I've seen couple try and fail. Usually good idea but bad execution.
Or a money grab

Hi, good question. We see ourselves as completely different from both Electroneum, as well as many of our other competitors. We aim to provide real solutions to the gaming industry, solutions that benefit everyone within the industry and community. From the developer to the gamer, everyone that is within the TriForce Tokens network will be able to benefit from its technology and its solutions.

Although we don't have 'mining', we allow developers to set tasks/quests from players that grants players rewards in the form of our own crypto-currency upon completion. So in a sense, I guess you could argue that would be mining to a degree? We also allow players to trade between one another, as well as honour each other through the worlds first honouree system. The system will allow players to send/donate real crypto-currency (TFT - our currency) to others as a form of gratitude or in exchange of services.

We are also currently building a anti-piracy engine. Working alongside Coventry University, we aim to help bring piracy down to a more manageable level for game development companies. We are also currently building a social engagement platform for the gaming community, that will bring the entire community under one roof, regardless of the platforms you play on. We aim to have a beta version of the social engagement platform ready for our community by Feb 2018.

I hope this answered your question? If you still want to know more about TriForce Tokens, I strongly suggest checking out our website and our whitepaper. I will provide links below for you.
