Want to keep testing your knowledge of gaming trivia? We've got loads more PC Gamer quizzes, on everything from healthbars to weird currencies to absurd patch notes.

If you're reading this website, you almost certainly use Steam. In fact, I'll go one further: you probably use it a lot. Valve's little app is the load-bearing wall of PC gaming at this point.

But when something becomes that ubiquitous, it's easy to take it for granted—and to simply stop thinking about it. How much do you really know about this program that you let control most of your gaming life?

It's time to find out—and perhaps learn a fact or two along the way—with our latest quiz. We've plumbed the depths of the entire history of Steam, from its humble beginnings to its industry-defining present, and fished up a bounty of trivia to test you.

Formerly the editor of PC Gamer magazine (and the dearly departed GamesMaster), Robin combines years of experience in games journalism with a lifelong love of PC gaming. First hypnotised by the light of the monitor as he muddled through Simon the Sorcerer on his uncle’s machine, he’s been a devotee ever since, devouring any RPG or strategy game to stumble into his path. Now he's channelling that devotion into filling this lovely website with features, news, reviews, and all of his hottest takes.
