Super Smash Bros for Wii U has sold nearly half a million copies in just three days.

According to Nintendo, Super Smash Bros sold 490,000 copies in the US over the three day period with the biggest shopping day of the year, Black Friday, still to come later this week.

“The Nintendo holiday is off to a great start, but there’s a lot of work left to do and a few more surprises in store for our fans," said Nintendo of America marketing and sales boss Scott Moffitt. "With great deals coming on Black Friday and Cyber Monday and great content like Captain Toad: Treasure Tracker launching next week, Nintendo will offer shoppers the best combination of fun and value this holiday season."

The Wii U has struggled since its launch late in 2012. Sales are improving on the back of several strong releases, but as of August, the console still only had an installed base of 6.8 million.
