Steam’s Top Games by Copies Sold (Week 28): Indies and Discounts Everywhere!

The Steam sales landscape for week 28 of 2025 was defined by the significant impact of aggressive discounting and the sustained popularity of indie titles. The primary thesis highlights that deep price reductions, often strategically timed to coincide with franchise marketing or upcoming sequels, serve as the most effective catalyst for driving high-volume unit sales on the platform.

Key findings indicate that indie titles continue to dominate the charts, with the co-op climbing game PEAK reaching 5.3 million total copies sold and the horror title R.E.P.O maintaining its status as the year's top-selling game with 16 million lifetime units. Furthermore, the data underscores the viability of DLC as a revenue driver, evidenced by the RimWorld: Odyssey expansion, which moved over 250,000 units in its launch week and is currently outperforming the title's previous content releases.

The analysis covers global Steam performance, with specific regional insights noting high engagement in markets such as the United States, Russia, and China. Methodology relies on proprietary platform data tracking unit sales, revenue, and player engagement metrics. The findings demonstrate that steep discounts—such as those applied to Jurassic World Evolution 2, Sons of the Forest, and Little Nightmares II—consistently generate massive spikes in volume, even for older titles. These promotions are frequently leveraged to build momentum for upcoming franchise entries, as seen with the transmedia marketing efforts surrounding the Little Nightmares series. Ultimately, the data confirms that a combination of viral indie appeal, long-term community engagement, and tactical pricing remains the most successful strategy for maintaining high visibility and sales volume on Steam.
