Up until now, the best way to use Steam on a Chromebook would be to run Linux. It doesn't really work all that well through Crostini, though, but it appears that Google is working on getting Steam supported on Chrome OS.
The news comes courtesy of Android Police, who had an interview with Kan Liu, the Director of Product Management for Chome OS.
It's not all flowers and roses though, as there are three primary factors that would notably hamper the attraction of installing Steam on a Chromebook: notebooks with Chrome OS typically have no significant GPU power, and the selection of AAA titles on Steam for Linux is quite limited (though there are some games that work).
What's interesting here is Google Stadia. With a platform such as the Chromebook and their limited hardware, one would expect Google to suggest players stream games rather than attempt to run them locally.
No time frame was given for when Steam is to land on Chromebooks. For now, this is just a project, so we'll have to see in due time what really comes of it.
