Sorry not sure you saw my last post, as I had missed yours.
Regarding DQVIII, Wikipedia links to a japanese page saying 4.9 m worldwide and 430k NA, and I thought europe had done similar numbers as NA. But I forgot EU actually sold more than NA, so it does seem a bit below 4m.
Do you know if the red/blue/green and gold/silver numbers include remakes and recent digital rereleases? Or was this solely the original GB releases?
All those numbers are the original releases, not even including budget reprints.
