Creatures is an Artifical Life computer game series made by Cyberlife, now called Creature Labs. The games is the series are Creatures 1, Creatures 2, Creatures 3, Docking Station, Creatures Adventures, and Creatures Playground. Creatures Adventures and Creatures Playground are more oriented towards younger players, and are mostly about exploration, and playing mindless mini-games. The other games are more oriented to breeding the Norns, while protecting them from Grendels. Creatures 2 introduced the ettin, which in Creatures 3 steals machine parts. Many expansion packs have been released for these games, and they are easy to make third-party addons for, as Creature Labs not provides full documentation of the game engine via the CDN, or Creatures Development Network. The original idea for the game was invented by Steve Grand and has since been taken over by market droids.
