Multiplayer Dungeon Crawler will use Myriadcoin:
Here is the link:
MyriadMaze.ComI believe this will be the first multiplayer game in the world to use a POW cryptocurrency.

Huntercoin?
Not really the same. Huntercoin was human mineable coin started in 2014. Interesting idea, but was highly susceptible to bots, priced crashed to less than 1% of it's original price and it eventually died.
This game will use Myriad (or 1:1 in game commodity with Myriadcoin proof of reserves) as an unit of trade.
You said first multiplayer game in the world too use a PoW coin. Huntercoin was literally a multiplayer game where every turn was a block, and even if it was bots those bots were deployed by multiple people, thus still multiplayer. Kinda semantics, but there's honestly probably other examples. I remember some doge based space MMORPG I think. Anyway, cool to see people building on myriad.
