The funny thing are Steam metrics, Anno 1800 got pulled day one on Steam but still managed to triple Anno 2205 peak.
Anno 1800's concurrent player counts on Steam peaked at 25,214 on launch day, according to Steam Charts. The previous title, Anno 2205, reached 7,401 peak concurrents on day one. We don't have data on how many people are playing through Epic's launcher or Uplay, but it's safe to say that a significant number of those early sales came through Steam.
Congratulations to Com_Raven and Blue Byte.
