I'd be surprised if there is a serious language that doesn't come with at least some semi-official style guide. But usually they are not universally followed and everybody just does their own thing.
You're not gonna like this but, some unique tech that makes a game look 5% better isn't making the experience better than access to mods, or being able to play 30 years old games on the same machine as a new game, or being able to play on mouse+keyboard.
Especially considering games that "exploit the PS5 capabilities" tend to be formulaic AAA games featuring gameplay mechanics that got boring 2 decades ago.
Is JavaScript a serious language? /s
Joking aside: One of Brendan Eich's books probably contains something resembling a style guide.
