We'll take Nintendoji too, please
Much like the Club Nintendo WiiWare Little Mac vs. Doc Louis!!, Japan is getting an exclusive for their Gold/Platinum reward -- a dungeon crawler named Nintendoji for DsiWare/3DS eShop.
It features a card based battle system, and based on the gallery below, it has a number of Nintendo references scattered throughout, like a green shell, DK barrel, and what looks to be Moo Moo Milk.
While not mind blowing, exclusive games are always an easy sell for me, and it's a really cool extra to get people to join Club Nintendo.
