I was born totally blind and there are actually even modern mainstream games that have implemented accessibility features extensive enough that they can be successfully played and enjoyed even by a totally blind person. Look at The Last of Us Part I and II, the new Forza Motorsport, Mortal Kombat 1, As Dusk Falls and others. I'm not saying this to criticize but rather as an interesting point to add to the discussion. All I'm saying is that it can be done but you need consultants who live with the impairment and are also experts in accessibility to do the job right, if it's interesting and relevant for your business. And also, please, don't assume. Although most of the assumptions made in the talk were mostly right, I mean yeah, I wouldn't be able to drive a car in actual traffic or watch fish in tanks as a blind person, I'm still very much interested in playing games. The Czech indie game 1428: Shadows over Silesia, available on Steam and GOG, which I worked on as a consultant and translator into English, also has full blind accessibility, so it can be done even if you're a solo indie dev.
