Super Mario Galaxy sells 500k in its first week

Super Mario Galaxy

's initial sales in Japan may have been a little disappointing, but that's not the case in the U.S. The game has sold 500,000 copies in its first week, which isn't too shabby of a debut for the portly plumber's newest escapade. Sure, the U.S. has a larger install base than Japan, meaning that the game should sell more, but even when put into context the U.S. sales for Super Mario Galaxy don't disappoint.

According to George Harrison, NoA's senior vice president of marketing, Galaxy is both the fastest selling Wii and Mario game in the U.S. to-date. Furthermore, with the excellentreviews that the game has been receiving, it's not hard to believe that the game will sell even more for the holidays.

We'll have to wait until February to see if Super Smash Bros. Brawl can dethrone Galaxy as the Wii's first week sales champ, but we certainly wouldn't be surprised (or upset) if it does. Even so, we decided to put a little Mario tribute video after the break.
