We have some sobering news for Switch owners looking to purchase the newly-announced wireless NES controllers.

A blurb on Nintendo’s website has confirmed some huge limitations on how the controllers can be used.

Please note: Nintendo Entertainment System Controllers can only be used while detached from the Nintendo Switch system, and only to play NES – Nintendo Switch Online games. Nintendo Entertainment System Controllers can be charged by attaching to the Nintendo Switch system.

While expected, it’s a little disappointing that Nintendo will not be letting other titles (like indie games) use the controller. Overall, it looks like these wireless NES controllers will only be useful for die-hard fans of NES classics.
