The recently released Super Smash Bros Ultimate for the Nintendo Switch has become the fastest-selling game in the series in the UK so far.

In addition, the new brawler is also the fastest-selling Switch title so far, thereby surpassing the combined launch sales of Pokémon: Let’s Go Pikachu and Pokémon: Let’s Go Eevee. Interesting to note is that digital downloads haven’t been included in the sales data – only physical sales are included.
