Steam Train Fest — Top 10 Demos By Player Count

With every official Steam sale, we take some time to check out all of the top demos. With the weekend for Steam Train Fest now arriving, we're taking a look at all of the demos based on their all-time peak player counts.

One thing that's worth noting is that we're removing anything that uses AI from this list, so it's entirely AI-free; we want to support developers who are keeping the industry human. You can learn more about our stance here.
