A new Nintendo DS game from Nippon Ichi Software lets you become the owner of a chain of convenience stores – managing your way to glory as you fight the advance of rival chains!  Entitled “The Combini DS,” the game allows you to go through your store’s inventory using the system’s touch pen.  The game is part of a series that has spanned multiple platforms, including Xbox 360 where the game is called “The Combini 200X.”  The new game is scheduled for a fall release in Japan.
