From a technical perspective No Man’s Sky hasn’t had an smooth launch on PC. But in terms of sales, it’s already one of the biggest launches ever of a game on Steam. Steam Stats, an official resource created by Valve, shows that 212,620 people were simultaneously playing No Man’s Sky on launch day so far. In North America and Europe alone the Steam servers were serving a combined 4.7 terabits per second as people downloaded the game.
You might be thinking: “Eh, that’s far less than Dota 2,” which is drawing just over 1 million concurrents in the middle of its biggest tournament of the year. And you’re right. But consider this: 212,620 players is at least 46% more than what was achieved by every other 2016 release at launch, and it’s possible that more people will boot up No Man’s Sky on Saturday or Sunday, when Steam activity is typically at its weekly peak.
