B.C.’s Quest for Tires is a 1983 video game developed by Sydney Development and published by Sierra On-Line. It was released for the Commodore 64, Atari 8-bit, ColecoVision, ZX Spectrum, MSX, and Apple II, based on the comic strip B.C. by Johnny Hart. The name of the game is a play on the title of the contemporaneous film, Quest for Fire.
The player takes the role of the caveman Thor, who has to rescue his girlfriend, the Cute Chick, who has been kidnapped by a dinosaur. To do this, he must travel on his stone unicycle through several levels. Each level involves Thor moving from the left to the right, avoiding various dangers.
A sequel, Grog’s Revenge, was released in 1984.
