Just as railroads swept the United States/U.S., leaving in their wake a west that was significantly less wild, so has Valve's Steam client spread across the personal computer/PC, centralising, simplifying and consolidating. What started as a way of administering updates has become a delivery platform so powerful that it has threatened to render even the big publishers' alternatives obsolete, an online community so well-supported that it sets standards even for those found on consoles, and a no-fiddling environment that allows your games, settings and saves to follow you from one PC to the next every time you log in. Looking back, such success seems inevitable, but in reality Steam was far from an obvious idea. Creator Valve was a developer, not a publisher or distributor, and the service's opening months were marred by bottlenecks and a frustrating online registration experiment. More interesting than the triumph, then, is the journey: what has made Steam such a powerful platform? Which forces shape its evolution? And how can it rewire not just the PC market, but the way that games themselves are developed?
