I have an idea.
Have any of you played the adventure game Myst? It’s not text, it’s graphics.
Well, I wonder if anyone intrested in cooperating to make a story-rich text myst game, related to the games.

Does Cyan – or whomever owns the Myst license – allow or encourage fan-made games?

I’m not entirly sure- so if someone knows, please post before we begin. I wonder if the same applies to freeware games, if they do not permit sold games. Also, one thing I know is true is that if we choose not to release it, it would be absolutly legal.
