The Nintendo Wii U only launched in the UK last month and it looks like the games aren't doing too well in the sales charts. The only Wii U games to make the all-format top 40 at launch were Nintendo Land and New Super Mario Bros. U which are in 26th and 36th place respectively.
Since the launch, there hasn't been any improvement in the sales of Wii U titles, with last week's sales charts showing off bad news for Nintendo UK. Both titles that previously made the all-format top 40 weren't in the new top 40.
Nintendo did have a game in the top 20, which was the New Super Mario Bros. 2 on the Nintendo 3DS which slotted into 19th place.
