Y U NO New 3DS?!?!
If you're not familiar with 3DS play coins, they're earned while a 3DS is in sleep mode and its owner walks around (or shakes the device wildly like a dirty cheater). For every 100 steps you take, you earn one Play Coin up to 10 coins a day and 300 coins total. Think of all the trophies you could buy!
