20. Space Giraffe
Released in 1981, Space Giraffe was similar to the classic Atari arcade game “Tempest” with updated gameplay and a new look. The throbbing neon backgrounds and light effects can make it hard to follow what’s happening on the screen. There are flashing lights, rave music, and seizure-inducing shifts in speed, sound, and color. Reviewers were polarized between people that praised the addictive gameplay and design and people that hated the confusing aesthetic and thought it was more like a bad acid trip!
