IGN writes: "The core concept behind Treasure World is incredibly innovative. The idea of using Wi-Fi signals to build up a collection is just as good an encouragement to get out and walk as Nintendo's Personal Trainer Walking, but instead of building up steps in a pedometer, you're scooping up invisible signals floating around in the air. I had a whole lot of fun wandering my neighborhood seeing what cool stuff I could collect, but I honestly wish there was more to the DS experience than just setting it to "scope" and picking up Wi-Fi signals. The music creation tool is pretty decent and the online community is surprisingly rich. But this game just begs for more in-game activities".
