That’s because you probably don’t remember Berzerk, a fantastic robot-blasting arcade game released by Stern back in 1980. Berzerk was the first coin-op ever to use computer-generated synthesised speech, a technology so new at the time that every single word the machine "spoke" cost over $1000 to record. The game itself was a riot – unlike almost every other videogame before and since, the enemy robots were as dumb as rocks, and would frequently kill themselves by walking into walls, shooting each other in the head, or being crumped by their boss, the bouncy electrified ball Evil Otto, and all of it accompanied by commentary in the robots’ Dalek-style voices. Best of all, they even called you a puff – if you legged it out of one of the exit doors before you’d zapped every robot on a screen, the survivors would taunt you with the cry "Chicken! Fight like a robot!"

A few seconds after your game ended, the machine would also attempt to persuade you to have another go by scarily claiming "Coins detected in pocket" in an, but Berzerk was so much fun, there hardly ever were.
