KINGDOM HEARTS -HD 1.5+2.5 ReMIX- briefly reached the top of Steam’s paid-game chart on Aug. 17, 2026. A screenshot posted to the Kingdom Hearts community on Reddit showed the collection in the No. 1 position after Square Enix gave Kingdom Hearts IV a late-2027 release window and showed new material from Pixar’s Coco.
The timing is clear. The size of the effect is not. Steam’s live top-sellers page also changes throughout the day, and the live position had already moved by the time the observation circulated. This was a dated snapshot, not a claim that Kingdom Hearts has permanently taken over Steam or that every game saw the same sales increase.
The No. 1 moment happened on Aug. 17
The community post records a specific moment rather than a vague claim that the series is “trending.” It shows KINGDOM HEARTS -HD 1.5+2.5 ReMIX- at the top of Steam’s paid-game ranking on Aug. 17. It does not provide unit sales, revenue totals, or a player-count comparison.
That distinction matters with a discounted game. A top-seller chart is a sales signal, while Steam’s live player count measures people playing at a given time. The chart supports a burst of buying interest around the Kingdom Hearts news, but it does not prove that the trailer alone caused the climb.
D23 gave fans a reason to catch up
Square Enix’s Aug. 16 announcement set Kingdom Hearts IV for late 2027. The publisher listed PC through Steam and the Epic Games Store, along with PlayStation 5, Xbox, and Nintendo Switch 2. The new trailer also confirmed that Coco material will appear in the game, adding Pixar’s Land of the Dead to the worlds shown for the next mainline entry.
Independent coverage from PC Gamer and GamesRadar+ confirms the late-2027 window, new combat footage, and the Coco setting. Pixel Twelve already covered the release window and Coco reveal in our earlier Kingdom Hearts IV report. This article is about the immediate Steam response, so the trailer’s story details do not need to be repeated here.
