Not sure if you're aware, but once you buy the maximum amount of Poke Diamonds in Pokemon Rumble World, you ALSO unlock a Diamond Mine which gives you 20 free diamonds a day. This is Nintendo's way of saying thanks for basically buying the game, as such a purchase is equal to a (discounted) 3DS cartridge.
AnonymousAs tempting as that might be there’s no way I’m spending over $30 for 3,000 Poke Diamonds
Also I have no money on my account or whatever
