You can get your hands on Legend of Legacyfrom developer FuRyuon October 13 in North America, and it sports a special launch edition. It’ll come with a box, a hardcover artbook, and a 10-song soundtrack. It will be limited to pre-orders and a “small” amount of launch day copies.
Otherwise, you can just get it digitally on the 3DS eShop for $39.99, which is the same price as the physical set. I love it when eastern developers do nice little incentives like this to encourage pre-orders, rather than take away content and sell it in a Season Pass.
