Which digital format of New Super Mario Bros. U Deluxe should I buy for Nintendo Switch? An Account or a eShop Code ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the eShop Code format.

If I buy the account format of New Super Mario Bros. U Deluxe, will the store provide all the activation instructions?

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

Why is the eShop Code of New Super Mario Bros. U Deluxe safer than the account format?

The eShop Code format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download New Super Mario Bros. U Deluxe to your game library. The account format requires more complicated steps and is more prone to errors during activation.

What issues can arise when activating a eShop Code of New Super Mario Bros. U Deluxe?
