Personal Computer Museum in Brantford, Canada, really enjoys Dragon's Lair in all its many, many incarnations. Bolton owns almost every version of Dragon's Lair ever released, which is saying a lot considering that game has been ported more times over the last 30 years than a Carnival Cruise ship. However, he hasn't got them all, telling Joystiq that he's missing the mobile phone version from 2005 (because it wasn't available in his area) and the Amstrad CPC versions from the mid-'80s.
The picture above contains 47 versions of the game and its sequels. Bolton mentions that the image doesn't contain the whole collection, as a few copies are in storage. We've listed every copy of the game featured in the picture after the break.
