With nethack slashem and larn, you have symbols show up on the screen each of which has a specific meaning. Learning those symbols and the games have similar symbol sets will make those games accessible. Another game called omega probably omega-rpg is accessible and similar to the three already described. The umoria or moria game isn't accessible screen writes are like tome bad for screen readers and tome is even worse since you have to try to run out of a cave and you're probably three levels in by the time you find the carpenter in order to stay alive long enough to complete that quest.
