The iPhone port of Myst has gone live. The game is priced at US$5.99, and the download size is extra large.

As we posted back in August, Cyan — the developer behind the puzzle-based series — announced it had a small team working on a port of it's 1993 point-and-click classic Myst.

The team may be small, but the game is not: It clocks in at a whopping 727 MB. "Big" iPhone games are typically in the neighorhood of 80 - 100 MB. (I Love Katamari was 84 MB!)

The first puzzle is figuring out why exactly the iPhone Myst port is so darn huge. We assume the answer is something about artwork, sound effects, music and developers taking the piss out of players.
