This is the fastest-selling Nintendo Switch software ever having over 6 million units sold in the first week of its release, compared to Pokémon Sun & Moon for Nintendo 3DS (did 7.2M before the end of November 2016).
However, players are having issues with national dex and the graphics in Sword & Shield, but despite that, most players are still having fun and are still enjoying it. Being Sword & Shield as the second set of mainline Pokemon games on Switch and the first to have Generation 8! Nintendo also mentioned that they have released 41 million copies of Switch units internationally.
Even though The Pokémon Company kind of put too much pressure on the deadlines on Gamefreak, I really hope that they will still be able to deliver the best for the fans!
