I have reason to believe Silksong's launch will be close to the top five of all time in Steam peak players. I'm not saying this just because of sheer wishlist estimates, but because of past releases of the same scale that fell between the one and two million concurrents range.
You could argue that the most obvious way to estimate Silksong player numbers on launch day, Sept. 4, is to look at wishlist numbers. However, Steam doesn't reveal wishlist counts, just followers. You could trust third-party websites that estimate Silksong is close to 5 million wishlists, but even if that's close to reality, it doesn't mean everyone who's wishlisted the game will buy and play it as soon as possible. That's why I believe it's easier to look at other games that were just as hyped as Silksong and how they performed after release. All numbers in this story are based on SteamDB's peak charts.
