Mac Rumors has a very good PPC session too https://forums.macrumors.com/forums/powerpc-macs.145/
I just really like Vogons, and would be happy if it became a gateway to all kinds of hardware...
I know there are less people interested in macs than anything x86, there are those who collect everything in this world, even toilets https://www.youtube.com/watch?v=hHqAvzGyy30
But look on the other hand, if the amount of people who just want solutions to play old games on modern hardware were really big (from a profitable point of view), a port of Wine x86 would already be available, to run transition era games from 16 to 32-bit, and even late 90's 32-bit games that have minor incompatibilities.
I believe the vast majority prefer to have the experience of playing on the original hardware anyway (psychology explains this, but I don't remember what it's called, nostalgia is greater when you can see and touch). I would never object to emulation and ways to work around compatibility that have come up here on the forums, I appreciate it very much. I'm just exposing my honest opinion, and some arguments from a financial (which would be very good for the founders of the forum) and cultural point of view. It was not my intention to upset anyone, my sincere apologies if I said anything that might sound insensitive.
