You can find the Nintendo Switch like almost any single system as a pack. With the advent of digital games, it is more common that the systems include 1 or 2 video games, others bring 1 digital and another in cartridge.
To keep in mind
You have to take into account the version we are buying. In the case of the Switch there are two models.
Nintendo Switch Classic
It's the one that gives us all the game versions (TV, Desktop and portable)
Nintendo Switch Lite
This console, smaller, only gives us the option of playing in portable and desktop mode, but we can't connect it to a TV.
