Laserdisk games
Anyone remember Dragon's Lair (YouTube video) or SpaceAce?
These were basically choose-your-own-adventure movies billed as arcade games. Despite the obvious limitations of strategy and interactivity, I still loved "playing" them.
I must've spent over 100 USD during one childhood vacation trip just on Cobra Command.
If the animation style of Dragon's Layer looks eerily familiar, it was one of Don "Land Before Time" Bluth's early works.
