Nintendo is reportedly ceasing sale of digital codes for its first-party titles through retailers across Europe, the Middle East, and Africa.
As reported by Nintendo Life, Nintendo confirmed that this was true at least for European retailers:
"After careful examination of the evolving European marketplace in recent years, Nintendo has decided to end the availability of download codes for its own-published software via retailers, effective 1st July 2020," Nintendo's statement reads.
"Customers will still be able to purchase Nintendo eShop funds, Nintendo Switch Online memberships, and add-on content such as the Pokémon Sword and Pokémon Shield Expansion Pass, at retailers across Europe. Download codes for Nintendo Switch software from other publishers will also still be available.
