Sometimes it feels like Nintendo makes New Super Mario Bros. Wii for the mainstream and Super Mario Galaxy (and now Super Mario Galaxy 2) for the rest of us. While the 2D Mario games tend to outsell the 3D ones, that doesn’t mean the recent Super Mario Galaxy 2 didn’t find an audience.

Nintendo held an online, condensed version of their E3 2010 press conference with analysts the day after the conference. Within, Nintendo of America president Reggie Fils-Aime discussed Wii’s momentum throughout 2010 and into the fall. Helping leading the charge? Super Mario Galaxy 2.

“In May,” said Fils-Aime, “we launched both Super Mario Galaxy 2 and the new Wii configuration…featuring either black or white hardware, as well as both Wii Sports and Wii Sports Resort. Super Mario Galaxy 2 is approaching 900,000 units here in the U.S.”

Nearly a million units for Mario’s second galactic outing on Wii in the US alone. Not bad, Mario.
