The Switch's performance this year has been impressive considering the platform's relative lack of third party support and the big first-party titles this year to date having been Octopath Traveler and the latest Kirby game. Nintendo's launch year first-party line-up, together with a rapidly expanding indie library, have proven almost single-handedly sufficient for the Switch to have a second sales year just as impressive as it's first. I think that right there is a testament to the innate appeal of the clever type of hardware that Nintendo went with this time around, as well as the amount of investment Nintendo put into their launch line-up this gen.
