Yes, to second Nolan,
Games, for the most part, move out of semantic HTML.
For some strange reason, people like to do games in React, when React is
not a gaming framework. None of the games that are built with React,
without a screen reader user testing them, that I've seen, are accessible.
Even the React website's tutorial is not accessible (although there is an
open issue on Github).
This is an area of interfaces WCAG guidelines don't apply to, and semantic
HTML breaks down. Almost all games, except for HTML-based games, will only
have an application element, with possibly some menus, and maybe an element
