Good points, it certainly needs to be done the right way. I like the ownership aspect of it with Splinterlands, where the cards that you earn/win can be sold in an in-game marketplace to others that are looking for cards to purchase for themselves. Players just getting paid to play a game is a different animal and left to more "professionals", which is why I like to follow Intergalactic Gaming, where those players are more high-level sponsored type of players that are competitive.
