The crazy coders at Valve had been making the monthly top lists manually this whole time, but no more. They've given their monthly top-releases charts a fresh makeover and you can scroll all the way back to the release of Half-Life 2.
At least with them being automated, they'll actually release the charts consistently every month now. Valve said with the upgrade you can expect to see them arrive 14 days after the end of each month. Since it's automated, you can also now scroll back as far you want.
The charts use both the Early Access and 1.0 releases, so some games might appear twice across the years.
There of course wasn't exactly much competition on Steam back in November 2004, with that being the only game released on Steam. This is long before Valve opened up to allow many more developers to put their games on Steam. Before direct publishing, before even Steam Greenlight.
With the refresh they've put the list up to 50 items, and when you scroll down on a full month they've also added filtering options now too like genre, platform and so on. DLC will also show up now too, if it's popular enough. Like with April 2025 that's newly live, showing a Call of Duty season pass.
When you go month by month from HL2...
"No new games released on Steam this month."

This is a heavily interactive web application, and JavaScript is required. Simple HTML interfaces are possible, but that is not what this is.A pity it isn't. For some things, if not most, simple HTML interfaces would be perfectly sufficient, if it weren't for the "design" and of course, "telemetry".
All I'm getting is a blue butterfly, and that was that.
Your JavaScript is off, to use the BBCode options please turn it on. Commenting will still work without! :)and thank you for that.
