Good list. At least RE is selling well, though their on-off commitment to transparency
does fiddle the numbers a little bit. RE7 is "the best selling" in the series but it looks like they got there by combining the Regular and Gold Editions, but RE5 has its three different versions, (Vanilla, Gold Edition, Gen 8) counted separately, which doesn't take into account RE4 having a Skyrim-tier number of ports to different systems, plus whoever keeps buying RE6. So it's more like,
RE5 - 11.8 mil
RE6 - 9.5 mil
RE4 - 9.2 mil
RE7 - 7.9 mil
RE2 Remake - 7.2 mil
RE3 Remake sold less than that, and well-deserved for being a downgrade. Should have been DLC to the RE2 Remake to begin with instead of forcing the $60 price point by attaching REsistance.

With DMC, counting each vanilla title's lifetime sales and re-releases we got,
Devil May Cry 4 + SE - 4.5 million
Devil May Cry 5 - 3.7 million
DmC + DE - 3.6 million
DMC 3 + SE + HD - 3.6 million
DMC 1 + HD - 3.46 million
DMC 2 + HD - 3 million
Not counting the Switch port for 3. So yeah, that's skirting close to 22 million units according to
their own financials (they've rounded up because the math puts it at 21.86), and God of War approached that number
8 years ago with 7 titles (5 installments, 2 "Collection" titles) (21.65mil).
DMC has always been rather niche, but I honestly hope they're content with their achievements and don't pull a Kobayashi with, "we wanted to market the game to girls, and take away the things girls don't like, like blood and gore and things like that". MHW, Megaman, and RE are their best sellers, so they can crank those out and try fishing for other IPs like Darkstalkers and Dead Rising. Something something Street Fighter, something something Dragon's Dogma.
I'd be down for a DmC 2 though. >_> Let's keep "Yamato cutting open portals", "Vergil using Doppelganger", and "Vergil having a massive and blatant inferiority complex" where it belongs.
