I agree so much with the points in this post, which are articulated shown very well, and am glad to see this kind of long-take on the subject. Showing visually some of what other games offer that GU doesn't really highlights how much we're missing out on in the way of fun and draw.
I know I have been happy to spend money regularly on other games where I can't even earn anything that can be taken outside the game or that lets me earn back some of the money. If GU could combine the pleasure of those games along with the unique things it has by being a blockchain game I can't see how it wouldn't improve the player experience immensely.
Hell, half of us would prolly pay a tiny bit of gods to do a quest where the only reward is getting to change our avatars, let alone anything fancier and more exciting.
