Tamagotchi
The Tamagotchi Connection is a virtual pet that was first released in 2004. It is unique from prior models in that it uses infrared technology to connect and interact with other devices. Using the device's infrared port, the virtual pet (referred to as a Tamagotchi) can make friends with other Tamagotchis, in addition to playing games, giving and receiving presents and having a baby.
Tamagotchis can have 6 levels of friendship, which can be viewed in the Friends List. These levels are: Acquaintance, Buddy, Friend, Good friend, Best friend, and Partner. If the Tamagotchi cannot find a partner from another device to have babies with, a matchmaker will come, allowing the Tamagotchi to have a baby with a computer-controlled Tamagotchi character.
Version 5 introduces a Dating Show game in which the user must play to gain a CPU partner.
