Despite the recent release of its first paid, single-player expansion, Octo, Splatoon 2 remains a multiplayer-first game for most of its community. Nintendo Switch’s online capabilities were free when the game launched, which helped support and expand the player base — and continues to do so. With the premium subscription service Nintendo Switch Online on the way, however, should players be concerned about a shrinking multiplayer field or, worse, a greater divide between experienced Squid Kids willing to pony up and tentative newcomers testing the waters?

Producer Hisashi Nogami doesn’t think so, he told Polygon. But he does anticipate some changes to how people approach the game once the Nintendo Switch Online barrier goes up this fall.
