Just as good as copy protection were long manuals. You might
learn something reading it.
Some manual based protection could be a bit vague.
E.g. 10th word on page 201
I can't say I think much of disc protection. Nothing funner than
a scratched up disc or busted floppy.
I don't have any real nostalgia for it. I like modern features
like automapping, or in game help.
I'm disappointed even the good games were pirated like
crazy. Some people will do anything to avoid paying for something.
