Steam's 20 Best Selling PC Games of 2015 Made $650m, Data Suggests

Independent sales monitor estimates PC sales for GTA 5, Fallout 4, MGS5, Witcher 3, Rocket League, and more.


Valve's PC network Steam generated close to $3 billion in total game sales during 2015, according to independent financial data.

Of that, the top twenty best-selling games are estimated to have brought in more than $650 million. Grand Theft Auto 5 singlehandedly sold about 3.8 million units, equating to $160 million, while Fallout 4 sold some 2.7 million units and amassed $122.5 million.

These estimates come from an independent marketplace analysis by Steam Spy owner Sergey Galyonkin, who in a blog post explains that his estimates are not completely accurate.

Galyonkin uses a web API to track the sales data of more than 3,000 Steam games that were released in 2015, and calculates revenue by using each game's lowest advertised price. That would suggest these estimates are conservative, and the final figures could be higher.

According to the Steam Spy data, Konami's latest blockbuster Metal Gear Solid 5 is believed to have made $41 million, while GameSpot's Game of the Year Witcher 3 brought in $38 million. Breakthrough indie hit Rocket League is estimated to have made more than $30 million.

Valve, which takes roughly a one-third cut from most games sold on Steam, is believed to have made close to $1 billion from all game sales in 2015, if the Steam Spy data is accurate.

Steam is the world's biggest core games platforms. In January, it was revealed that the platform's peak concurrent user number had passed the 12 million threshold.

Galyonkin estimates that more than 350 million games were sold across the platform in 2015.
