Once they learn a concept you can communicate with your Norn. Scattered through out the environment are toys to keep the Norns amused and different types of food to eat. There are 40 types of objects in all to interact with but not all are friendly. There are poisonous plants to avoid and a nasty creature called Grendels who will steal food from your Norns and hurt them. Then the older Norn started learning to play with some of the toys on his own.
Creatures represents an amazingly complex artificial intelligence programming.
According to the authors, CyberLife Technologies , there is no way to fully predict what will happen to the Norns once they begin to reproduce. You can breed many generations of Norns and even trade the Norn eggs with others over the Internet. CyberLife claims that Creatures is the result of true neural net programming. Neural networks try to simulate the brains thinking process in which individual regions work independently and with each other to adapt to new situations. Each Norn will have different health patterns, learning abilities and a personality based on the experiences he or she has and the interact the owner give them.
