One point that I see rarely mentioned in analysis of NFT games is that in my experience every game has some kind of player engagement half-life. After a while the games get stale, new twists, takes on the original premise of the game are necessary to engage the player. Attrition is the consequence and most often other games from other companies innovate where the original failed to innovate.
It is beyond me why I would spend more real money on these games, than let's say a classic boxed game. But maybe I am getting old.
