Monster Hunter Rise has passed 8m now. I would assume the PC release is what pushed it over 8m.
Capcom Co., Ltd. (Capcom) today announced that Monster Hunter Rise for Nintendo Switch and PC (Steam) has shipped 8 million units worldwide.
The Monster Hunter series consists of hunting action games that pit players against giant monsters in a beautiful natural environment. Beginning with the first title in 2004, the series established a new genre in which players cooperate to hunt ferocious monsters with their friends and has since grown into a global phenomenon with cumulative sales of the series exceeding 78 million units shipped as of September 30, 2021.
Monster Hunter Rise was released for Steam, a PC platform with a broad global user base, on January 13, 2022*. Featuring high-resolution 4K support and voice chat functionality for PC, the game provided a fresh hunting experience that garnered praise from players while additionally growing the player base across a wide range of countries and regions. This, combined with sales of the Nintendo Switch version that was released in March 2021, drove global shipments of the game to surpass 8 million units.*Japan Standard Time
Going forward Capcom looks to further expand its player base with Monster Hunter Rise: Sunbreak, a massive premium expansion for this title that is slated for release in summer of 2022.
Capcom remains firmly committed to satisfying the expectations of all users by leveraging its industry-leading game development capabilities.
So half million sold since October, guess it did less than a third of numbers from World on its first 11 days as it crossed 10 million mark on August 20 after Capcom stated console sales to be 8.3 million: https://www.vg247.com/monster-hunter-world-10-million-copies
I'm starting to agree with Kyuu, it's becoming harder to justify Nintendo exclusivity. Rise sold only ~400k more than World in Japan, in a console that had 2.5 times the PS4 userbase and with a franchise know from being very strong on handhelds. Sales in Japan are from enough to offset the huge amount of sales missing from Playstation owners, specially when PC version sales aren't looking to be as big as World was. Next entry is probably going to be cross platform, first launching on PS5 e Series S/X, months later on PC and Switch 2 even if this means anemic software sales in Japan due to lack of interest in PS5. With MH popularity already degrading in Japan I see no reason to prioritize its home market anymore
