I don't really understand why someone would want to do this.

A group of gamers from around the world created a 100,000+ keystroke script for speedrunning The Legend of Zelda, which was used by a blind gamer in Ontario complete the game. Jordan Verner, who is blind, posted a video of himself playing Zelda and asking for help to complete the game. This inspired other gamers to spend two years composing a script that Verner could follow...

I mean, i can understand the desire to play a video game. What i can't understand is how this would be in anyway fun for this guy. He's basically just following instructions on pushing buttons for several hours. What's the reward? He doesn't get the fun of figuring out the puzzles himself. And Zelda wasn't designed so that he could hook it up to a machine that would describe what was going on in the game, so what's the pay off for successfully completing a dungeon?

Wouldn't playing on the MUD be more entertaining than following a 100,000+ list of button pushing instructions?
