Most of them are successful with their launches but the stability and consistency is where they're questionable. Not that a lot of them really survives for that long. And that's why with projects like OP is proposing, I don't think that it will take a long time for the market or even the game alone. Well, it's for the users to tell if they are good enough and the developers of it should be strong and firm with what they're working on. The consistency of the community should be maintained and provided by the devs of it on how they cater the needs of the demand of their gameFIs.
From what I've seen and felt, games projects lack in the - game - department, if analyzed and compared with normal games.
I hope this will change sooner or later.
We can just hope for the best but we will never know if most of them adopts to what's needed by the gaming community. There's so much to improve but because they're connecting it with 'fi' finance or money and crypto, that's how the whole setting is being changed. The motivation should be with the game and how its potential community that it's being built should be prioritized and not with the milking scene that we're usually seeing mostly with all of the game fi projects that are being launched during the bull run.
