Secondary Peace Kingdom is a simulation game developed by 반지하 게임즈 for the Android platform. In this game, players collect a variety of goods through second-hand transactions.

The game starts with simple items like jeans and MP3s, and gradually progresses to more valuable items such as helicopters, apartments, and even things like America. However, if players try to buy everything at the listed price, they won't be able to survive in the used peaceful country.

To succeed in Secondary Peace Kingdom, players must negotiate and offer low prices to sellers, carefully observing their reactions and taking calculated risks. The game constantly challenges players to find the best deals and make profitable transactions.

Secondary Peace Kingdom offers an engaging and unique gameplay experience, where players can immerse themselves in the world of second-hand trading and test their negotiation skills. With over 500 downloads, the developer promises to add new content to keep the game fresh and exciting.
