Fun read. I loved these games as a pre-teen/teen.

Since I'm a cynic in general:

> Cyan was likewise disinterested in pursuing other solutions that would have been even easier to implement than panning rotation, but that could have made their game less awkward to play...

I disagree with this paragraph.

I think back then, I thought this was intentionally helpful. Thinking on it now, I also think it was part of the character of Myst that would be too risky to lose for Riven.
