Treasure World is an adventure game for the Nintendo DS, blending exploration with augmented reality. Its unique genre could be described as a GPS-driven treasure hunt. Players explore their real-world environment while their DS captures Wi-Fi signals, transforming them into in-game stars. These stars unlock a variety of treasures, providing tools and decorations to customize the player's in-game space. As players collect more items, they can also interact with whimsical creatures called Star Sweepers. The game encourages outdoor activity and creative play, offering a novel gaming experience.
