For those who are too lazy to check My Nintendo rewards page, here's the list of the recently added discounts:
North America
- 15% off Luigi's Mansion: Dark Moon - 600 Platinum points
- 15% off Super Mario Galaxy 2 - 300 Platinum points
- 15% off Pikmin 3 - 300 Platinum points
- 15% off Dr. Luigi - 230 Platinum points
- 15% off Mini Mario: Minis on the Move - 150 Platinum points
- 30% off Triforce Heroes - 100 Gold points
- 30% off Tomodachi Life - 80 Gold points
- 30% off Wonderful 101 - 70 Gold points
- 30% off DKC Tropical Freeze - 50 Gold points
- 30% off Metroid Prime Trilogy - 50 Gold points
Europe
- 10% off Fire Emblem Fates - 20 Gold points
- 20% off Captain Toad - 600 Platinum points
- 40% off Captain Toad - 100 Gold points
- 20% off Animal Crossing: New Leaf - 600 Platinum points
While there's no denying that the North America lineup there is pretty solid, I already all of those games but Mini Mario: Minis on the Move. I might consider getting the latter near the end of June, since I believe I might enjoy this one and I could bag 20 Gold Points just by spending around $12 CAD with the discount (which would be at $14.09 CAD otherwise).
European's newly added discounts are pretty slim, but I can see why they would appeal to some people. Since it's easy for someone to get 20 Gold Points, Fire Emblem Fates discount seems to be an interesting choice.
