To the extent that games are made available for MacOS/ARM in the first place (admittedly a sticking point), it looks like these machines will be able to play most of them reasonably well. Certainly much better than most of Apples previous machines with integrated graphics or low end discrete GPUs.

iOS games/apps run on Apple Silicon Mac, so that by itself opens up a huge gaming market.

Casual gaming market.

In other words, the biggest gaming market.

Maybe, but distinct from real "gaming".

A game is a game. There is no "real gaming". Apple Arcade with a Xbox controller paired to a Mac is actually a fun gaming device for some types of gamers.

Genshin Impact is a great game that is on iOS in addition to "real consoles". Oceanhorn 2 is an amazing game that was originally on Apple Arcade and brought to Nintendo's "real console".

There is also quite a number of ports that I think you aren't aware of.

There is a difference between Tetris on Facebook versus Dota or CSGO on PC. The later is "real gaming", the former not. The border might be a gradient.

It's like calling yourself a programmer because you can set a timer on your VCR. (dated but still accurate)

And since when CSGO is a GPU-demanding game?

You think "real games" are for "hard triers only", but it's just your point of view.

Mine and many others. Rightfully so, see the example.

GPU was not the issue here.

umm there are more ports than you think.

I work on multiple OSX machines, servers run linux, and i have a single windows machine just got the few games that can't be run elsewhere.

If porting IOS games is easy then gaming for most people shouldn't be an issue.

I feel like the demand for desktop versions of simple phone games is pretty low.

Mac users who hope to play anything from their steam library or dual boot Windows are going to be very disappointed.
