Half-Life 3 is just the hot exclusive Valve needs to propel SteamOS past Windows

A little over 20 years ago, Valve was getting ready to release a new Half-Life game. At the same time, the company was trying to push Steam as a new option for players to download and update games over the Internet.

Requiring Steam in order to play Half-Life 2 led to plenty of grumbling from players in 2004. But the high-profile Steam exclusive helped build an instant user base for Valve's fresh distribution system, setting it on a path to eventually become the unquestioned leader in the space. The link between the new game and the new platform helped promote a bold alternative to the retail game sales and distribution systems that had dominated PC gaming for decades.

Today, all indications suggest that Valve is getting ready to release a new Half-Life game. At the same time, the company is getting ready to push SteamOS as a new option for third-party hardware makers and individual users to "download and test themselves."

Requiring SteamOS to play Half-Life 3 would definitely lead to a lot of grumbling from players. But the high-profile exclusive could help build an instant user base for Valve's fresh operating system, perhaps setting it on the path to become the unquestioned leader in the space. A link between the new game and the new platform could help promote a bold alternative to the Windows-based systems that have dominated PC gaming for decades.

Not another Steam Machine

Getting players to change the established platform they use to buy and play games (either in terms of hardware or software) usually requires some sort of instantly apparent benefit for the player. Those benefits can range from the tangible (e.g., an improved controller, better graphics performance) to the ancillary (e.g., social features, achievements) to the downright weird (e.g., a second screen on a portable). Often, though, a core reason why players switch platforms is for access to exclusive "system seller" games that aren't available any other way.

Half-Life 2's role in popularizing early Steam shows just how much a highly anticipated exclusive can convince otherwise reluctant players to invest time and effort in a new platform. To see what can happen without such an exclusive, we only need to look to Valve's 2015 launch of the Steam Machine hardware line, powered by the first version of the Linux-based SteamOS.

At the time, Valve was selling SteamOS mainly as an alternative to a new Windows 8 environment that Valve co-founder Gabe Newell saw as a "catastrophe" in the making for the PC gaming world. Newell described SteamOS as a "hedging strategy" against Microsoft's potential ability to force all Windows 8 app distribution through the Windows Store, a la Apple's total control of iPhone app distribution.

When Microsoft failed to impose that kind of hegemonic control over Windows apps and games, Valve was left with little else to convince players that it was worth buying a Windows-free Steam Machine (or going through the onerous process of installing the original SteamOS on their gaming rigs). Sure, using SteamOS meant saving a few bucks on a Windows license. But it also meant being stuck with an extremely limited library of Linux ports (especially when it came to releases from major publishers) and poor technical performance compared to Windows even when those ports were available.

Given those obvious downsides—and the lack of any obvious upsides—it's no wonder that users overwhelmingly ignored SteamOS and Steam Machines at the time. But as we argued way back in 2013, a major exclusive on the scale of Half-Life 3 could have convinced a lot of gamers to overlook at least some of those downsides and give the new platform a chance.

A little push

Fast forward to today, and the modern version of SteamOS is in a much better place than the Steam Machine-era version ever was. That's thanks in large part to Valve's consistent work on the Proton compatibility layer, which lets the Linux-based SteamOS run almost any game that's designed for Windows (with only a few major exceptions). That wide compatibility has been a huge boon for the Steam Deck, which offered many players easy handheld access to vast swathes of PC gaming for the first time. The Steam Deck also showed off SteamOS's major user interface and user experience benefits over clunkier Windows-based gaming portables.

Still, the benefits of switching from Windows to SteamOS might seem a bit amorphous to many players today. If Valve is really interested in pushing its OS as an alternative to Windows gaming, a big exclusive game is just the thing to convince a critical mass of players to make the leap. And when it comes to massive PC gaming exclusives, it doesn't get much bigger than the long, long-awaited Half-Life 3.

We know it might sound ludicrous to suggest that Valve's biggest game in years should ignore the Windows platform that's been used by practically every PC gamer for decades. Keep in mind, though, that there would be nothing stopping existing Windows gamers from downloading and installing a free copy of the Linux-based SteamOS (likely on a separate drive or partition) to get access to Half-Life 3.

Yes, installing a new operating system (especially one based on Linux) is not exactly a plug-and-play process. But Valve has a long history of streamlining game downloads, updates, and driver installations through Steam itself. If anyone can make the process of setting up a new OS relatively seamless, it's Valve.
