It is a good concept to eliminate the in-game ads, I am also annoyed with those but one simple way of tackling that is by not connecting the phone to the internet when you play. But it depends to the games that we play and if your games are needing to be connected to the web then that's all you have to deal with. Anyway, there is not that much success rate for these gamefi's. Just like this study made by coingecko, 3 out of 4 of it fails based on the study done in 2023.
