My Tamagotchi collection consists of many varied pets, new and old, inexpensive and pricey, and of all colors and sizes. Each of my Tamagotchis has a special personality, and they are all treated like individuals.
I usually play with only one or two Tamagotchis at a time, pausing them if I need to focus on real life for awhile. When I'm not playing with them, my Tamagotchis are turned off and have the batteries removed.
I've been collecting Tamagotchis since 1997, and I always keep up on new releases too. I also try to keep an eye out for good deals on vintage pets to add to my collection.
