There's people who would buy a more advanced version (e.g. M3 Pro instead of M3, etc.) for gaming. Many people want MacBooks for work, but also like to game, and buying two separate computers is annoying. I have two separate computers because I am in that category so in theory it sounds pretty cool to be gaming on my Mac in the future. But to give up my Windows gaming PC I would want at least 80% of the games I want to play to be available on Mac. That is a long journey
