Ys Strategy is a true real time strategy title that makes use of the DS's dual screens and stylus to provide a smooth interface for a genre that game consoles and portable systems have traditionally had trouble with. One screen displays a map and all your resources, while the other shows the game field and various icons for all your possible actions. Using the L button, you can switch the views between the top and bottom. The game is controlled with the touch pen, as you directly select characters and objects and then point to the desired action.
