Sensory cues in games, more often than not, are intended to be distractions ... except when they're required by (poor or inconsiderate) design for certain tasks. Visual or hearing impaired people don't have the option to use both sound and lights. For them, it's either substituting light for sound (or vice-versa) or nothing at all.
It's a bit disingenuous and egocentric for an able-bodied person to cry foul about allowing non-able-bodied people to use assistive devices - to experience enjoyment of the media - especially when the technology is available and intended to be inclusive when it's absence is exclusive. Using the same logic extolled above, I suppose it's unfair that visually impaired people get white canes and service animals, and hearing disabled people get TTY communications and flashing lights instead of doorbells, just so they can reasonably attempt to independently function in society - never mind attempting to enjoy the same things able-bodied people do.
For an exercise in empathy, try playing one of your favorite fast twitch-based first-person shooters without sound at all. Completely disable all sound ... unplug the speakers or disable them in software ... and then see just how successful or competitive you are with only onscreen cues. Now imagine you are forced to play that way competitively against other players who can use sound every time. Kind of sucks, doesn't it? Your choices are to not play at all or to play with an assistive device if one is available. Wouldn't you rather share the joy you experience while gaming instead of shutting others out?
I'm all for assistive technologies that help those with disabilities, but not at the expense of
ruining all multiplayer games. That sacrifice is just too high. (...and I don't even play multiplayer games anymore, in large part because of streamers and hackers)
This very much is in the same vein as cheating at a multiplayer game,
especially, but not only if used by those who don't need it.
I'd really like there to be ways for those with disabilities to enjoy life, hobbies, games and other things as much as possible, but if I am forced to make
that choice, then I'm afraid it is going to be rather one sided.
Mark me down as sympathetic, but opposed to the cost in this instance.
You simply can't make everything fair or better for those with disabilities. It isn't possible. A person with a disability simply won't be able to do all of the things a person without one can, and no one can change that. There is - for instance - a reason we don't issue drivers licenses to the blind or hire blind bus drivers.
By all means, add assistive technologies everywhere it is possible, as long as those assistive technologies are not harmful to the 99.6% to 99.8% of people (in this case) who don't need them. I'm sorry if that sounds harsh or "ablist" but that's where I stand, and my mind will not be changed on this issue.
People can't expect the world to change for them, regardless of their circumstances. And they
especially can not expect this when it ruins things the world cares about.
