Ashadelo beat me to it, but it's worth remembering that Raiders a spin-off, not Splatoon 4.

It's kinda like how Monster Hunter Stories or the Zelda Warriors titles wouldn't be expected to hit as big as the mainline entries in those franchises.

Almost 500k physical copies and hardware sales more than doubling isn't bad at all for a spin-off.

In other news, Mario Kart World hit 3m physical this week too.

@curl-6 Here's some extra info (sell-through) to complement your data. Little bit shocked by Splatoon only selling through 40-60% of its retail copies, though I'd imagine Nintendo didn't want another scenario of shortages similar to Pokopia, Tomodachi, or Rhythm Heaven.

More like no Splatoon 1 scenario where they were forced to publicly apologize for not producing enough copies.
