Newer packages will in theory always be better, that doesn't really matter which distribution or use case (gaming or not) one has.
Even if Debian were generating packages the second a pull request was accepted and making it available to everyone and any one it wouldn't change that the next pull request would, in theory (without regression) be more up to date.
If people have to wait 1s or 1 year, for gaming or not, they can have fun.
If hardware is not properly supported though it's a different issue. It means people need to buy hardware that is well supported. It's not specific to a distribution.
I'm playing old and new games on the SteamDeck and it works even if I don't update it. That's how things should be, that's how things already are.
Anecdotes, even if important personally of course, showing things don't work in a specific context don't make a trend. There are plenty of things that don't work well on Debian but also on Arch, Mint, etc and of course on Windows too. It's very annoying but I don't see how that helps.
