I think I will go for Enjin coin, and I've also been reading some good things about Ice rock. When it comes to Enjin I really like their project as a gamer myself, and if they manage to achieve all their goals, I think they will be huge. I played wow for a while, and items are incredibly important for us. The idea of being able to pass items across platforms, or be able to sell them, looks amazing to me.
As for Ice Rock, I still need more details before I decide whether to invest on them or not. But their goals are very good, so if they can pull out their mining farm on those Russian bunkers, and at that price, they should get huge.
