Not trying to be the contrarian; Same game will likely play far better on a Windows platform. There is clearly losses via Rosset2 in comparison to W10. I also expect an increase over the Intel Macs. Nor are many games well optimised for macOS.
I very much agree will be dependant of the players interest. My interest is far & wide from FPS, RTS to strategy and many more. Right now I'm deeply engrossed in S.T.A.L.K.E.R. Anomaly. Could I play on a Mac? Possibly/probably via Wine, M1 I seriously doubt.
Yes there's more games due to time, yet the choice and quality pales compared to the dominant platforms. TBH the performance & hardware is in place, however the cost of game development has spiralled. Similar to films sadly just become a numbers game
I've posted some links to source ports of old games. If I want to go hard at Doom 3 it would be on the M1 as it excels. More so than my PC can, which is way more than competent. Point being it's again one of few, nor can you or I change that.
As said I wish it was different, it's not...
