PEAK was June's top Steam game by copies sold, but SEVEN games climbed to over a million

Things have really heated up on Steam, and not just because of the heatwave that’s got the whole Alinea team praying for winter.

PEAK performance (sorry)

As we covered in last week’s newsletter, co-op climbing title PEAK is reaching incredible heights right now. It sold 3.1 million copies last month alone, generating $17 million in revenues.

Indie titles in general are continuing to smash it, as ever. There’s even a cohort of Steam players who play pretty much every co-op indie, with plenty of crossover:

• 61% of PEAK’s player base on Steam also played R.E.P.O.
• Around 40% of PEAK players have played Content Warning.
• 30% of PEAK players have checked out Chained Together or Lethal Company.
• Co-op sells on Steam, especially if it’s weird, wacky, and – perhaps crucially – streamer-friendly and shareable via short-video platforms.

Chinese FMV dating game Revenge on Gold Diggers (情感反诈模拟器) took June’s #2 spot with 1.3 million copies sold. As the game is only available in Chinese, 73% of its audience comes from China. Around 10% is in the US – mostly Chinese-speaking expats, presumably.

Rematch scored big last month

Rematch sold 1.1 million copies last month and generated revenues of just under $30 million on Steam alone.

Thanks to our unmatched pre-launch Steam metrics, we saw Rematch’s success coming, as seen in this article we contributed to for our friends at GamesIndustry.biz.

Rematch took a strike where others fumbled the ball. Titles like Knockout City and Destruction AllStars took cues from Rocket League but misread the playbook, focusing on flash over the football fundamentals.

Rematch, on the other hand, stays grounded and puts football at the forefront, appealing to both sports and competitive action fans, with data showing strong crossover from Rocket League and FC 25 players.

At Rematch’s core is a simple set of mechanics that are immediately accessible, yet designed with the kind of depth that really rewards precision and mastery. Rematch is a football-infused evolution of the fighting game formula.

Read our newsletter to find out why we think it was smart of Rematch to forgo free to play at launch.

Quick hits: These games also sold over a million – and they’re all diverse and target different audiences

Among June’s other million-plus sellers on Steam were:

• Elden Ring Nightreign (#4), which sold another 1.1 million copies to hit 2.5 million sold on Steam overall (on top of the 1.3 million on PlayStation). Our data shows that Nightreign’s DAUs on Steam are declining. But Nightreign – which was partly an experiment to train the next generation of FromSoftware leaders – has generated over $84 million on Steam alone. And on a lean budget to boot.
• Stellar Blade (#5), a PS5 port that we covered in detail here, sold 1.1 million in its release month. Over half (54%) of its players were in China. Developer Shift Up’s decision to price locally in China and dub cutscenes in Chinese clearly paid off.
• R.E.P.O (#6) also sold another 1.1 million last month, bringing the indie’s grand total to 15.4 million sold. Like we said earlier: co-op horror sells when done right. And R.E.P.O’s $121M in revenues suggests it was – indeed – done very right. A timely price drop from $10 to $8 helped R.E.P.O shift over 70K copies in one day at the end of the month.
• **Dune Awakening (#7)**_ sold 1.1 million copies in its launch month alone. Funcom announced this milestone this week, but if you’ve been following our coverage, you saw it coming.

June was clearly a big month for new launches on Steam, but July has some high-potential hits of its own – some you might not have heard of.

A quick interlude: July games to watch

Based on our July pre-launch Steam wishlist data, the following three games are on track to be three big July Steam launches:

Alright – back to the ranking.

New indie chapters, an old indie, and an old Star Wars game round off Steam’s June top 10

Toby Fox’s Deltarune Chapters 3 and 4 finally arrived on June 4, marking a major milestone in the game’s long development arc. Deltarune sold 788 K copies in June and brought in over $15 million.

Around 40% Deltarune’s Steam audience is in the US – and 63% of buyers had already played Undertale. The legacy of Deltarune’s predecessor runs strong.

With over two million players still waiting and wishlisted, **Deltarune hasn’t peaked yet.** Many are likely holding out for the full release, but these middle chapters prove that the game so far can stand on its own in segments.

Meanwhile, EA has once again leaned into its now-regular end-of-H1 fire sale strategy. In June 2025, Star Wars Battlefront II force-jumped back onto the Steam charts, landing at #9 with 751 K copies sold. This is a result for a title that originally launched in 2018.

The spike in sales was driven by a steep 90% discount, part of EA’s broader seasonal pricing push. For a fraction of its original price, players received not just the base game but a version packed with every cosmetic ever released.

The offer was aggressive, and clearly effective. The spike on the right of this screenshot from the Alinea platform (reach out here for a trial) shows just how much of an impact the Battlefront II sale had:

EA knows these games still hold appeal, especially when bundled attractively and timed to seasonal sales windows.

Rounding out the top 10, **Stardew Valley harvested another 583 K copies sold** on Steam in June, also driven by a discount – -50% to $7.50.

Discounts aren’t unfamiliar territory for the farming sim, as our data shows that Stardew has a proven track record of spiking in sales during discount periods.

Want to discover how pricing data affects game revenues or copies sold on Steam and PlayStation? Our platform has that data. Let us know and we’ll show you.

Our data shows that a similar price point back in early 2023 produced nearly identical results. The takeaway is clear: Stardew Valley remains one of the most consistently performant legacy titles in the indie space, with discounting still an effective lever for engagement and revenue.

It’s a testament to both the game’s long-term appeal and its evergreen visibility on storefronts. Even nearly a decade after release, it continues to convert new players at a remarkable rate, particularly during major sales events.

Few titles in any genre demonstrate this level of staying power. Whether driven by word-of-mouth, mods, or ongoing goodwill, Stardew Valley proves that smart pricing and a quality foundation can keep a game relevant well beyond its launch window.
