Rand Miller is probably one of the most influential game designers you've probably never heard of. He, along with his brother, co-founded the company Cyan Worlds. Cyan is the developer of the title Myst and subsequent titles in that series. With 12 million copies sold to date, the simple (but beautiful) point-and-click adventure game has impacted the public perception of videogames to an unprecedented degree. As you might imagine, Mr. Miller had a few things to say about the closure of the online version of Myst, URU Live.
