Your Nintendo DSi is going to do more than just play games out of the box. Built-in apps for photos and music will provide minutes, if not hours of fun. Expect the same of DSiWare.
Already available in Japan, the online DSiWare shop lets Nintendo DSi owners download bite-sized games at bite-sized prices. That includes micro session games like the Korogashi Puzzle Katamari Damacy from Namco and Phantasy Star 0 Mini from Sega, alongside Art Style series puzzle games Hacolife and Decode from Nintendo.
