Larian’s Swen Vincke posted a tweet yesterday showing the game hitting 500,000 concurrent players, making it the third most played game on all of Steam He said that he told IT to only expect 100,000 concurrents at max.
Why is it a problem that IT was not prepared for so many concurrent players? Yes, it has multiplayer, but it's mostly a single-player game. Did they pull a Diablo?
