In my opinion. If there is an MMORPG that is really good and integrated with crypto and world currencies. It will be a really good to invest in that game. Because it will be like a second world but on a virtual aspect. I hope that someone reads this message and makes a game just like that. And i hope its a really good and dynamic game with in-game currency that you can exchange into real world money.
Noticed this topic just now. I just wanted to let you know that I have completed for 85% such a world as an old school 2d rpg.
