Tamagotchi
Another 90s relic that simulated owning a pet, just like the modern day Poo.
First model of Tamagotchi needed a lot of your time or they would die, forcing you to reset and start over.
The company estimated that a Tamagotchi is sold at every second, and since then they sold over 70 million.
The game was first created for teenage girls to simulate the idea of having a baby and teach them how hard it is to take care of one.
