Not videogames, but my first suggestion would be to look at
$1 which has a large directory of audiogames which are generally based on sound alone, with no or very little video to begin with.
Videogame-wise I'm afraid it's pretty bleak. I play fighters like Tekken, Mortal Kombat, fighting games based on anime etc. because they are generally well supported by sound cues, and the arenas are confined by their edges so there's not a lot of walking/platforming going on. One of them, Skullgirls, even interfaces with screenreaders so you can hear the menu being narrated.
Outside of that, it's a lot of hit and miss. 2d sidescrollers tend to work reasonably well if there's not too much platforming, thenthere's Pokemon Crystal Access which makes Pokemon Crystal speak with a screenreader.
A relatively recent game is The Last of Us, part 2, which is a ps4 game that is entirely accessible as a bit of a first for videogames, especially of that complexity and genre.
Finally there's games like the Jackbox party pack games, that through playing the actual game rounds on a phone allow you to use your phone or PC's accessibility features to play the game.
A technique called OCR, Optical Character Recognition, can be used to try to scan static text in order to have a screenreader read it out loud. This works best when the text doesn't move, but requires the game's output to be on your pc somehow. Think the Xbox app that lets you stream a game's visuals, similar for PlayStation games, and for PC games that already happens by default of course.
Finally, there's a genre of games called collectively referred to as text-based games. Terms to google there are MUDs, text adventures and choose-your-own-adventure style game.
I hope that helps you out some :)
