I agree that a fun experience should be first. The creators of the game are overly fixated on economy manipulation whereas for games with economies (real money trading) even though it's not supported or banned, regardless it still happens. Those games don't pay attention to the economy.

MTG (legal), Like every mmo (illegal.) Some action rpgs (diablo etc.) League of legends too.

Games utilizing crypto should be fun game first, economy second. As for a game that succeeds on that aspect? yet to be found.
