Will it be abandoned? Yes. Especially if the game design itself doesn't interesting. Do note, as you said yourself that some people play games to get rid of boredom, but the essential part of gaming itself is whether the game is playful or not, if the game is shitty, people will not play it even if they earn some money. On another hand, people who solely seek profit will come into them. Some popular games like CS GO already have a loyal community, and the game itself is legendary. With that in mind, we know that there is a platform that give the player an earning if they play the game.
I agree, I once be a part of a game that was available in Steam, a gaming website where paid and free games can be downloaded online. It is a game that is kinda boring and not for all and they pushes to make it available in crypto, only few people got interested in the game most of the people just buy the coin because of the people behind it, now the game development is over it is now abandoned.
