It’s not so much that people are focused on gaming distros, it’s more that gaming distros historically haven’t been much of a thing, and gamers generally had to use windows for their gaming, because the linux experience was limited and sub-optimal. Even dedicated linux users would keep a windows partition/machine that they used for gaming.

That’s not true anymore, as basically anything without kernel level anti cheat works on linux, which means that a huge amount of folk that would have moved to linux earlier, but couldn’t, are now coming over.

Which is to say, it’s not so much that there is “so many of them”, it’s more that, they’re coming over in a big wave, because they’ve been there for years, but haven’t been able to move until recently, and now, they know that there are distros out there that look and feel like something they’re familiar with.

Cachy at least doesn’t do flatpaks out of the box.
