I’m not a game developer, but I honestly most of these settings are more or less taking a constant from a config file and putting in some UI to explain what they do and allowing the user to edit the values themselves. That doesn’t take much time and frankly is something the most junior dev could do during some downtime.

Sure, they might need to do some testing of the use of different values but I imagine they already spend a good bit of time tweaking these constants when determining their optimal values. I’d really like an example of an accessibility feature that the OP thinks has absorbed a lot of development time to implement.

I honestly feel strongly in the opposite direction. This specific is thing my absolute favorite trend in gaming.
