If you want to play games for the major game publishers, then you either get a console or a PC. Steam has some incredible games, both old and new that are simply not available on Macs. Conversely, as I said before, imo, iOS games are more casual pieces of fluff meant to pass time.
Also the Epic games store gives away at least one game every week for free. I always grab them because some of them are AAA titles. It's depressing how many of them are PC only with no Mac version.
