They created Myst, which was for many years the most popular game of all time. Several pretty successful sequels followed. Then they frittered away many years on several iterations of a mostly-failed MMO. In 2005 they laid off all employees but two. What the heck happened?

There must be a little life left, since they recently released Myst for iPhone. But they don't get much ink.

EDIT: this is a reply to a now-deleted comment, wondering what Cyan is.
