I think it's a pretty cool idea. I think what you're thinking of is turning it into a CLI/DOS sort of game or something, correct? At least, that's what I think of when you mean games that old. Something very old like Nethack/ADOM. I have a pretty bad attention span so I don't know if I'll run with this learning opportunity, but I like the idea. Gonna toss it on the study list.
Not a dev for this game either btw just a driveby commenter.
