Ok numbers?
123.6K x2 = 247K that would put it roughly in the top ten on Steam. I would say that's pretty good, considering huge game launches like Grand Theft Auto V and Fallout 4 were in the 360-470K range of peak players. However, these games have had their records for years and I've noticed that more recent games are pushing numbers close to this over the years such as Monster Hunter World and Hitman 2.
Monster Hunter World also released around 6-7 months after the console version (GTA V was released 18 months after the console version) and was the debut of the series on PC.
(Unfortunately dismissing
Kathy Rain and Kholat due to being given away for free and alleged trading card farming inflating the player numbers)
However, that 123K record for Borderlands 2 was 7 years ago, and to my knowledge that would have been one of the highest peak player counts seen on Steam at that point in time.
7 years on, PC Gaming has become significantly larger, so its not entirely certain how much potential a highly anticipated title such as Borderlands 3 could have really had. Perhaps the game could have done better on Steam, especially since the PC Gaming community appear to be pretty divided over the Epic Games Exclusivity stuff going on, but those player numbers sound pretty good for a game shrouded in controversy to say the least.
We're also kind of just guessing player numbers at this point if you expected it to do significantly better, due to this being something we'll never really know. (Unless the Steam release hits these numbers).
Perhaps it could have exceeded GTA V's and Fallout 4's numbers, and there's still time for the game to do this now as it's the weekend and the game just came out. Everyone will want to get a piece of this over the coming days.
