Creatures Adventures is a game about caring for and observing members of a fictional race of creatures called norns. The game begins in the hatchery of a house where the norns live. When the baby norns hatch, it is the player's responsibility to care for it by feeding and clothing it, watch over it by making sure it stays out of trouble, and reward or discipline it as necessary. The latter is carried out using the ever-present stickler and water jet icons: the first tickles the norn which it likes; the second sprays water, which the norn has an aversion to. The player get the privilege of naming your norns, dressing them, and playing with them. Also monitor multiple norns which explore independently of the others.
Eventually, the norns grow up and strike out to bigger and better adventures. Meanwhile day turns to night and seasons change during the game. The norns will also pair off and procreate in order to lay the groundwork for more norns that the player will eventually oversee. And sooner and later, the norns will die of natural causes and be buried in the backyard of the norn house, at which point the player gets to start fresh with the new norn generation.
The game features extensive parental controls which allow parents to create game files for different family members complete with passwords. The parental controls also allow limiting each family member to a certain amount of playing time each day as well as specifying bedtime.
When Creatures Adventures is installed along with Creatures Playground, another title in the series, they can be merged together to form the game Creatures Village, which was also the name for the remastered compilation that holds both games.
