The release of New Super Mario Bros. 2 will usher in a new digital era for 3DS by being the first retail game you'll also be able to purchase and download via the eShop.
And Nintendo wants you try out the new-school digital method, and is offering a small reward for doing so; double the Club Nintendo Coins.US gamers who purchase the game via the eShop can redeem 100 Coins on their Club Nintendo accounts - double the usual 50 that brick and mortar purchases will get.
That's not a huge amount - 50 extra coins is about enough to get you a few rubbish screensavers. But if you're saving up for that 1200-Coin Game & Watch, every little helps. All the Ts and Cs are through the source link.
The game's out in US on August 19 - weeks after the July 28 street date in UK.
