Some games don’t even have fucking KEYBINDS, which the most basic of accessibility features.
This will only change when stores (like Steam) start cataloguing these types of features and letting people setup default filters to hide all games without them.
The users have to make them hear that releasing any game without basic accessibility options is unacceptable. This will only happen when the majority is pushing for it, not just those that need the options.
Until then, make sure you leave a negative review and get a refund when you see this kind of thing, even if the game is otherwise good. Pirate the game instead if you still want to play it anyway. They have to be told that this is unacceptable.
