Dragon's Lair, when you look back on it, was a corporate grab in the arcade world. Disney-level graphics when all the other games were 8-bit, and the worst gameplay ever in an arcade game...because it was made by someone who'd never set foot in an arcade.
The only competition it has for worst came later when that hologram game came later where you're a cowboy shooting...Native Americans. Another turd that was all graphics and nothing else.
