16 or more first party, and, yes, the cards were expensive, but you really only needed one big one. But look at Nintendo charging 60 bucks per game, and you need to buy multiple sd cards, but people aren't complaining. And the support is there because it's their only machine. They quit the 3ds when the switch came out.
These are the types of games I like to invest time in. A good, narrative driven experience is what I like to look for to add to my library of games. Multiplayer lasts for a month, but a great story is timeless.
I have most of these originals, but this is a great selection for a mini console. They could have easily added 20 more, but I am happy with the selection and I have mine pre ordered.
