Here is a partial game idea that I thought up, but which is not something I expect to write. (Also, this idea alone isn't enough to make the game.)

Anyway, this game is a text adventure (also known as interactive fiction). However, there is one twist that affects how it is written (and, in particular, is why this idea wouldn't work for a point-and-click):

The protagonist is blind.

This means that, when descriptions of rooms, areas, and events are written, visual descriptions can't be used. Things can be described in terms of sound (you hear a loud thud), smell (it smells rather rotten here), or perhaps touch or taste (the wall feels rather rough here).

Being blind also limits the actions that can be performed slightly; looking at something isn't possible. Reading isn't possible unless it's in Braille (or something similar). Most other actions can be performed, and some actions (like touching objects) become more important when you can't see.

As for actually making such a game, I would want to have an actual blind person be involved in writing the text for the game. Also, there would need to be some plot other than "the main character is blind"; we need something more to make things interesting. (Maybe there's a killer out there, or maybe you're exploring a cave.)

Has any game of this sort actually been written?

Nice idea.

My first thought here is that blind or not, you HAVE to have a lantern or you'll be eaten by a grue.

The protagonist could benefit from some aid for senses, and the obligatory white stick could be modified to do more than just prevent them from falling down a hole.

Perhaps they could have remote control of a helper or two (Duskers?). I know you are thinking about a text adventure, but along those lines.

Plots...
1. Not blind, but...Protagonist has been kidnapped and had a metal head covering fitted. Then they hear the kidnapper die.....

2. Blind....They were being driven somewhere remote, the car crashed but they survived the accident.

3. Blind, survived an attack / accident in a jungle.

Most scearios that immediately come to mind seem to be based on survival. Most text adventures make a LOT of use of what can be seen and a lot of use of treasure hunt plots. Not so easy with a blind person.

I would suggest Googling Infocom, in particular their title, "A Mind Forever Voyaging". I think that has similar themes, although not blind, I sem to remember the protagonist is secluded and has limited contact. In any event, anything to do with Infocom has more imaginative descriptions, and should help to fire your imagination further.

Hope this helps.

Check out a game called The Nightjar. You're not blind, technically, but there's almost no light in the game, so it's functionally similar. Bonus: Benedict Cumberbatch.

The protagonist is blind in Perception, but you use echolocation to "see" sort of like Daredevil does in the comics and tv series. Quick search suggests it's not out yet, but close.

I cant see this concept going anywhere :o)

There was an XBLA game many years ago that had you playing as a blind monster in a cave. Intriguing concept that panned out poorly since you had no idea what kind of plane your character moved on.

There's a game that I played about a year or so ago called Inquisitor's Heartbeat. You have to make your way through a series of dungeons while avoiding sentries, but you are completely blind. The ambient sounds of the dungeon are all you have to help you find your way. As you move you will either hear the sounds of your own footfalls indicating that moving was successful or you hear a dull thud meaning there is a wall in that direction. Beyond this you may hear water dripping, rats scurrying or someone breathing. When you get near the exit you will be rewarded with the sounds of birds in the distance. There was some odd graphical clues, but I found that closing my eyes as I played helped much more.

This doesn't really count but in one of the Ultimate Marvel games there is a small 'tutorial' where you play Daredevil, who is obviously blind.

You're tasked with going into a room and taking out four or five baddies, however, for the entire level the screen is totally black. Whenever one of the baddies makes a sound you see a quick blue flash indicating where on the screen the noise came from. You use these flashes to navigate around, find your targets, and take them out.

It really does work for that level but technically the player is still using his or her eyes.

In ye olden days, there was a MUD that had supernatural characters, and every room and item was geared for using 5 senses and more. Thus, when you'd find yourself blinded temporarily, you would need to navigate by touch and scent and sound, or some other special sense (daredevil radar ability, there was a spirit you could summon that would act as your eyes, telling you a short version of things (so you'd miss details)). I only played around with it a few times before moving on, but anyway, the point is this can be done, It just takes time and effort.

Isn't this any dark room in a text adventure game?

This concept actually sounds interesting, but the trouble would be to make the story engaging enough that the player doesn't get bored trying to figure out everything.
I'd be willing to write it myself or collaborate with anybody who's interested, and I actually know 3 or 4 blind or visually impaired people I could get involved.
