There's nothing wrong with trying to make money from games, and one could argue that you should try, especially if you're trying to run a studio, pay salaries and bills, or at least pay for the tools and assets you use to make games! Of course, gamedev may not be the best way to make money, but that's a separate topic. In any case, I've only made about $50 here, but I only do pay-what-you-want and I've received no payments after adding webplayers for each game (so there may be some UI or psychological issue there). Also, I don't put much time into marketing. However, I just like how itch.io is set up and the developer spirit here, and it supports badges that link to other app stors, so I use it as my main portal and portfolio and it's possible that it's driven some of my earnings on the App Store, for example, and I'm sure having my own projects helped me get other work.
