In this game, you will play a role of a small business owner who has to manage his store and the people who come in to buy cards. You have to keep an eye on everything, as the customers may ask for some products that you don’t have in stock. You can also find some of them in the shop that you have opened in another city. 

There are different types of cards that you can buy, such as e-cards and games cards. You can also buy other things, such as money, gas, food, and other goods. The game is based in a city that you can visit and get some of your business done.
