Those that wanted DSi games that use its extras games look here.
Swedish-developed Ghostwire will let you use the DSi's camera to hunt ghosts in the real world through augmented-reality gaming, developer A Different Game announced today. In the adventure title, gamers will use the DSi as a portal to the astral plane to find and collect ghosts that exist all around them. The game will also use the DSi's built in microphone. Once you find the ghosts you will have to figure out why they are haunting your world so you can help them find peace.
"The Nintendo DSi platform is perfect for this game" says Anders Bergman, lead game designer of Ghostwire. "This allows us to enhance the integrated real-world experience with the combination of camera, microphone and touch screen."
