Well, Capcom talked about how they expected more sales in the initial launch period, but later (a year later or so) they talked about how they misinterpreted the data, and how the industry has changed into way more steady period of sales instead of just focusing in the first months, like when the industry was physical based first.Weren't RE7's initial sales tagged as "disappointing?" I remember that being a huge issue even if the game cost a lot less to make than RE6.
No matter, I'm glad it sold that high now. I really enjoyed that game and brought me back to the Resident Evil franchise so it's great to see people picking it up.
It has been definitely a big success for Capcom.
