in fact at one point I was going to enter one of the best games that they had considered from the beginning, but for reasons of life I had to do a lot of corresponding errands with my 4-month-old daughter and she left a lot time on it, after I wanted to do it, something prevented me, then I saw that the price fell more than 60%, then I believed even lower, the discord and telegram of that game said that it was only a strong correction and that it was safe to enter, which was cheaper, but when these things happen, everything is already damaged, there are cracks that cannot be repaired and the price went to less than 1 USD, the number of people they lost was gigantic, from that moment I did not believe anymore in NFT games.
I would guess that the purchasing is the main problem because it has very little utility that attracts people. Lets take Axie in our hands, they charge you SLP for breeding but we will breed and breed and breed and one day there will be countless of them, so the price would have to go down significantly to cover that, you can't have the same axie prices at 100k total axie versus 1 million vs 10 million.
It means that breeding will not be profitable, which means that you can't really use SLP that way. They dropped the amount of SLP you can earn, so that the price would go up, so that you can earn less but worth more, which failed miserably since people already stashed so much. All in all, if you do not provide a good "buy this token because of this" mechanism in any play to earn game, that token will be earned but not spent like you assumed it would.
