Nintendoji is an interesting game because it’s so limited. You can only get this downloadable 3DS/DSiWare game if you’re a platinum or gold level Club Nintendo member. Nintendo of Japan will send members who have this status a code which they can redeem to claim for this game.
Players move through dungeon floors and use a card game-like battle system. The dungeon has sacred treasures to collect and when you return to your home base you can place an offering to improve your stats or gain new abilities.
