Screens released earlier this month from Tales of Graces show that the game will not take place on the Wii alone. A minigame will be included that will beam to a Nintendo DS through the Wii's DS Download Play feature.

The minigame will be titled Kamenin Merchant. RPGamer has screens of Kamenin available here, showing that it looks similar to the style of Children of Mana. Players will explore randomly generated dungeons while defeating monsters to level up and collect items and equipment. After defeating bosses in Kamenin Merchant, the results can be transferred back to the Wii, which will enable rare items to be more easily acquired in Tales of Graces. The minigame can be played by up to four players at once, too, using DS Wireless Play.

Namco Bandai plans to make Kamenin Merchant available on DSiWare for gamers that do not own Tales of Graces, or plan on purchasing it in the future. Tales of Graces will be released on the Nintendo Wii in Japan on December 10, 2009. North American or European release plans have not yet been discussed or divulged.
