How it’s built
- List each game release and assign it to the April–March year it fell in, for Game Freak titles and Creatures titles separately.
- Do the same for the start of each Japanese card series: 2016, 2019 and 2023.
- Each card series started 14–63 days after its matching game, in the same financial year.
What we assumed
- Release dates are as listed, mostly from Wikipedia lists.Wikipedia is a secondary source; key dates are well known, but small errors are possible.
- Pokopia (2026) is counted as a Game Freak co-development.That credit comes from a single source.
- Releases are mapped to an April–March year.That is the founders’ financial year.
Sanity check
Because cards and games land in the same year, yearly timing alone cannot tell a card fee from a game fee; only volume can. Japanese per-year card-set counts were not obtained.
Where it comes from
Our calculation from other figures in the trainer’s notes.
Show the working
- DLC only FYs: year to March 2021 (2), year to March 2024 (3)
- No release FYs: year to March 2016, year to March 2025
- ILCA not Game Freak: BDSP (year to March 2022)
- 2016-12-09 − 2016-11-18 = 21 d
- 2019-11-29 − 2019-11-15 = 14 d
- 2023-01-20 − 2022-11-18 = 63 d
- Release dates mapped to Apr–Mar fiscal years
