Today I was digging around poloniex and the crypto gamecredit peaked my interest. So naturally I went investigating and found this : http://gamecredits.com/ I know that some real deep sloothing there for sure :P anyway. While looking at their site I noticed that they supposedly had already integrated into a game called fragoria fragoria.com
Despite looking kind of childish it still peaked my interest vaguely so I checked it out. Amusingly however once I got into the game I discovered that it hadn't really been integrated yet :( Ah well it was worth the dig.
