Now that i think more it sounds like a good idea to change the name to  a name that is not associated with a single game but to the whole e-sports scene.
Then the dev's can make a betting site, sell games for coins etc. Make some battle bot that does not have to be in game. After all people do wanna see who is better and are willing to bet on that, you just have to figure out how to give them that
For some of the games you can upload replays etc.
The point is that there are a lot of options as long as the dev;s wanna continue working on the coin.
Waiting to hear from them !
