Genie, hold on. Mom and Dad said I could play Yars' Revenge. Revenge? Who's getting even with who? You'll see. Yars' Revenge is a video game cartridge you have to buy separately to play on the Atari Video Computer System. Your parents hook it up to the TV. Now you're supposed to be Yars fighting a bad co-top. Woo-hoo! You got him, Genie. Can I still play? Tonight, Steven. This is the Atari Video Computer System. Yars' Revenge and other video game cartridges are each sold separately.
