From the more mainstream ones, The Last of Us 2 has famously implemented accessibility. I haven't played it, as it's one of the only games for the PS4 that is accessible, but people are saying that it almost plays itself when accessibility is enabled, taking away part of the enjoyment.
Other mainstream games are getting accessibility mods, Hearthstone has a really great one. Audio Quake, an accessibility mod for Quake, was also quite popular back in its day.
Text based games, from Infocom's interactive fiction to MUDS and MOOs are also pretty accessible, a significant portion of people still playing them are blind.
