Dragon’s Lair was really impressive first time you saw it, the local arcade had to stack another TV on top of the cabinet so the crowd could watch the gameplay. A week later there were several regulars who could play the game through which was also a spectacle. It was a few months before you could walk in and play it freely. The arcade owner must have made a mint - I believe it was the first game I played that cost fifty cents.

It is unfortunate that neither the laserdiscs nor their players have held up well - none of the arcade museums I visit have a functioning cabinet - but the emulators work and there is a version for iOS that plays well also.
