Number of games released on Steam 2004-2025

The online gaming platform Steam was first released by the Valve Corporation in 2003. What started off as a small platform for Valve to provide updates to its games has turned into the largest computer gaming platform in the world. The platform initially released only a few games in 2004, but this number has progressively risen in the ensuing years, reaching over 15,000 in 2025.

Steam’s PC dominance

When you think of PC gaming, you automatically think of Steam. With such a wide range of games on offer, from traditional online multiplayer shooters to farming simulators, there is something for every gaming taste on the platform. As a result, gamers flock to Steam in their millions, with the platform registering over 132 million monthly active users in 2021. The global nature of the platform can be seen by the wide range of languages spoken by its users. Whilst English was the most spoken language for most of the platform's history, this changed as over 33 percent of users in October 2024 claimed Chinese as their platform language.

Steam’s biggest games

Counter Strike 2 was the most popular game on Steam during 2024. The first-person shooter averaged almost 685,000 players per hour, a significant lead over its successor, Counter-Strike 2. The game was also third among the 2024 list for peak number of concurrent players — CS2 reached over 1.74 million players in a single hour in its peak, with Black Myth: Wukong claiming first place with over 2.4 million peak concurrent players.
