If you register Smash Bros 3DS or Pokemon OR/AS (2. october - 12. january) and a 2DS/3DS/3DSXL ( 11. september - 12. january), you will get a free download code for one of the following games:
Monster Hunter 3 Ultimate
The Legend of Zelda: A Link Between Worlds
Yoshi's New Island
Kirby: Triple Deluxe
Mario Golf: World Tour
Mario Party: Island Tour
Pokémon Art Academy
Glad I wouldn't let my two youngest kids register their 2DS consoles after I was stung registering my XL for points. Then they make offers like this, but you can't use any previously registered consoles before the offer started.
