Not only is Hollow Knight: Silksong actually coming, but it will be here in a little over a week. The sequel will sell millions of copies, maybe even more than the original. If it even comes close to achieving that, it will move the Hollow Knight series' lifetime sales beyond the combined sales of every Metroid game ever.
Hollow Knight and Metroid are both Metroidvanias, a genre that was named after the Samus-led Nintendo flagship series. However, as highlighted by The Game Business's Christopher Dring, if Silksong performs well on the sales front, which is almost guaranteed, the series will have sold more copies than every game in the Metroid franchise combined. That's despite there being 17 Metroid games so far and only two Hollow Knight ones.
Team Cherry recently told Bloomberg that the original Hollow Knight has sold 15 million copies. I imagine that number has gone up again since they quoted that number, as more people have flocked to the OG since last week's Silksong news, a sales spike that led to the game smashing its concurrent player count on Steam. By comparison, the best-selling Metroid game is Metroid Dread, becoming the first game in the series...
