Digital versions of Nintendo's games seem to be showing up in more and more places for purchase these days and, as of today, Humble Bundle can now be adding to that growing list.
Right now the selection features a mix of 40 different Switch and 3DS titles, from recent games like Super Smash Bros. Ultimate and the Pokemon: Let's Go titles to even Virtual Console titles like Super Mario Bros. and The Legend of Zelda. All titles are selling at their full MSRP, and none qualify for charity contributions either.
Nintendo titles are eligible for the $5 discount you get with Humble Bundle monthly subscriptions, but beyond that, there doesn't appear to be much of a difference from any other retail store (online or brick and mortar).
Humble Bundle has not stated whether third-party and indie Switch and 3DS titles will be offered at some point, so hopefully we'll hear more regarding that sooner versus later.
