I'm not a fan of blockchain games yet. They have nothing interesting yet. Opportunity to earn? Well, so myself. I will not say that this way of spending time will bring profit. And interest? Well, in a snake, you can play on nokia 3310. And it will be much more epic.
I have never played any Blockchain games and spend some money to put in it except for cartesi, and that was when they were running a giveaway for being listed in binance. I think you are right that blockchain games is not work investing and just a waste of money and time that could have been spent in something lucrative.
