How it’s built
- Took Nintendo’s unit figures for each pair: for example Ultra Sun/Moon 9.28 million against Sun/Moon 16.34 million, a ratio of 0.57.
- Compared remakes with the main game before them: Omega Ruby/Alpha Sapphire against X/Y was 0.87; Brilliant Diamond/Shining Pearl against Sword/Shield in each launch year was 0.84.
- Compared Legends: Z-A after 5.5 months with Legends: Arceus after 2 months: about 1.0.
What we assumed
- Launch-year totals compare titles at different ages on sale.Each pair notes the months on sale (for example 4.3 against 4.5). Where the gap is large, as with Arceus at 2 months, the ratio understates the younger title.
- Nintendo’s copies sold to retailers stand in for player demand.Nintendo reports only sell-in, on the same basis for all titles, so the ratios are at least consistent.
Sanity check
The pattern: a same-region sequel reached 0.57, remakes 0.84 to 0.87. Legends: Arceus, an old region in a new format, did better than its follow-on status suggests, which weakens a simple “new region or nothing” reading.
