Top Games by Steam Followers

Followers on Steam reflect a strong indicator of ongoing interest in a game, and during this period, a clear group of titles stood out. Among them were well-known titles such as Resident Evil Requiem, Atomic Heart 2, and Grounded 2. These games were expected to perform strongly, given their recognized franchises and large existing audiences.

Other games made a surprisingly large impact, including ILL, a body-horror first-person shooter; Chronicles: Medieval, a vast medieval sandbox; and Pragmata, Capcom’s sci-fi action game first revealed in 2020 and now making a return. The Expanse: Osiris Reborn also performed well, securing a place in the Top 10 following its debut at the Future Games Show. The game’s setting, based on hard science-fiction books and a TV series, seemed to connect with players.

This range of titles highlights the appeal of a mix of well-established franchises alongside new properties. The strong performance of The Expanse: Osiris Reborn underscores the ongoing popularity of narrative-rich, atmospheric adventure games and shows how a game can attract a following, even when it is revealed at a lesser-profile showcase.

Top Games by Steam Wishlists

Looking at wishlists — a key indicator of future purchasing intent — the trends were broadly similar to the follow numbers. Mainstream titles and well-known franchises generated large wishlist numbers quickly. Mortal Shell II and Code Vein II, for example, performed strongly in this metric, reflecting ongoing interest in the “Souls-like” subgenre. Nioh 3, a samurai-themed action game, also secured a large number of wishlists.

Some more unconventional titles performed well, reflecting a growing interest in unique game worlds. Into The Unwell and Mouse: P.I. For Hire, alongside Boxing, a game presented under the title Felt That, all made a strong showing in wishlists, indicating that players are increasingly interested in different, stylistically ambitious titles.

Median Wishlist Trends by Showcase

Analysis of the data shows a clear pattern when it comes to the average or “median” wishlist increase for each showcase. The Summer Game Fest led all events, adding a median of 42,500 wishlists per game in the first 5 days after the showcase. The Xbox showcase followed with 29,300 and the PlayStation showcase came in at 22,800. Some games were not available on Steam immediately after their announcement, which made a direct comparison challenging in a few cases.

Other events, such as Future Games Show and PC Gaming Show, performed well above many of the smaller showcases. Day of the Devs and Wholesome Direct were also strong performers in their own context, reflecting the growing appeal of independent and small-studio titles alongside big-budget games.

Platform Distribution Among Announced Games

Platform support for the games revealed during Not-E3 highlights the ongoing dominance of PC and, more broadly, the growing significance of Steam. The majority of titles were slated for release on PC, reflecting the platform’s large and engaged community of players.

PlayStation was a close second, while Xbox followed just behind. The number of titles confirmed for the Nintendo Switch 2 remained small, reflecting the ongoing scarcity of development kits and the policy of backward compatibility for future hardware. Nonetheless, this highlights a key consideration for developers when choosing platforms to target with their games.
