The strange thing about Ellisons writing, is that I just can't reread it. But the movie is great for watching anytime.
Did you ever play the computer game version of 'I Have No Mouth but I Must Scream'?
BTW per the commontery on the DVD when test screened 25% of the audience did'nt understand the ending at all (where did Quilla June go?). The movie big cheeses wanted to 'fix' it. Thankfully the director prevailed. I've personally explained it on the way out a couple of times.
No I never have played the game. Ellison was one of my favorites growing up. I saw him speak at a local college and he was a blast.
