Steam’s revenue-based top lists are up. In addition to the annual list, they now also have another one grouped by month of release:

The top tier is really surprising to me. Witcher 3 is still selling that well? I’d thought Divinity Original Sin 2 was a far more niche title than that. And Rainbox Six Siege, wtf?! I’d heard the scuttlebutt about Ubisoft “supporting it well” and “rescuing it after a disastrous launch”. But I had no idea they meant that a game released in 2015 was one of the top 12 most successful games on Steam in 2017.
