We already know that Super Smash Bros. on 3DS has been a success for Nintendo, selling over 2.8 million worldwide since its launch, but according to the September NPD report, the game also helped increase 3DS sales by 55 percent month-ove-month in the US.

Super Smash Bros. on 3DS sold over 705,000 copies with only two days of data for the September NPD, making it the “No. 4 best-selling software SKU for the month” according to Nintendo. And that’s also factoring in digital sales, which Nintendo says accounted for 135,000 sales.

Wii U sales were also bolstered month-on-month with an increase of “nearly 50 percent over sales in August.” Nintendo attributes the increase to strong performances from Hyrule Warriors and Mario Kart 8. Hyrule Warriors has sold over 190,000 copies, and it would have made the NPD top 10 in the US if rankings were based on an individual SKU basis. And Mario Kart 8 “sold nearly 60,000 combined units in its fifth month on the market, bringing its lifetime total in the U.S. to nearly 1.2 million total units.”

Nintendo will likely have a strong finish to the year as well with both the Wii U version of Super Smash Bros. and Pokemon Omega Ruby/Alpha Sapphire due out in November.
