Space Invaders [SEP] Development
"Space Invaders" was created by Japanese designer Tomohiro Nishikado, who spent a year designing the game and developing the necessary hardware to produce it. The game's inspiration is reported to have come from varying sources, including an adaptation of the mechanical game "Space Monsters" released by Taito in 1972, and a dream about Japanese school children who are waiting for Santa Claus when they are attacked by invading aliens. Nishikado himself has cited Atari's arcade game "Breakout" as his inspiration. He aimed to create a shooting game that featured the same sense of achievement from completing stages and destroying targets, but with more complex graphics.
