Lattebot

(There are server settings where you can change the prefix or allow lattebot to only respond in certain channels)

This bot's main game is centered around selling milk that you get from cows to make money. With that money, you can buy more cows, land to have space for more cows, certain upgrades in order to make production faster, machines that refine the milk in order to increase it's values, you can upgrade your tier so you can unlock more items and upgrades...

It's basically get money to get more money.

It also has a few small fun features such as hugging people, clearing messages, (if you have the required permissions), a leaderboard and answering your messages with an image.

In addition to that, it has a built in system to submit bugs and suggestions and a quest system
