Seems like a fun collection of minigames! Not sure if this is true, but I heard that NOA's president wants to see how well it sells before it's released in America.
Personally, I love the DS because it has: -A different way to play games with the touch screen. -Online. -Games/Sequels from the series that I like (Animal Crossing, WarioWare, Picross, Yoshi's Island, etc.). -Touch Generations games.
