'For all your gaming needs, KookminTree' presents the big data game rankings for the second week of September 2025. KookminTree curates these rankings weekly based on search engine big data. Let's dive into what games have been capturing the attention of players this week.

Mobile – The Top 3 Hardens

Welcome to the second weekly big data game ranking report for September 2025. 'Vampir', which debuted in the top spot last week, is looking comfortable in its lead. While the gap between it and second-placed 'Roblox' was narrow just a week ago, Vampir has surged ahead in this week’s tally, effectively silencing any fears of being overtaken. With a fresh launch and rapid-fire updates, it’s hard to imagine any other title challenging its throne throughout September.

Of course, things could shift if a major new rookie arrives. Keep an eye on 'The Starlight', 'Goddess Order', and 'Aetheria: Restart'. All three are set for September releases and have been generating significant search volume even before their official service begins. However, given that Vampir maintained a comfortable lead over these contenders during its pre-registration phase, don't expect a new number one to emerge so easily.

As Vampir pulls away, the mobile game Top 3 is beginning to settle. With Vampir leading, followed by Roblox and third-placed 'Mabinogi Mobile', the gaps between these positions are becoming quite difficult to bridge. Furthermore, while fourth-placed 'Lineage M' is on an upward trajectory, the distance to Mabinogi Mobile is already significant, meaning the current Top 3 hierarchy looks set to stay for the foreseeable future.

Elsewhere, we’ve seen growth for 'Lord Nine', 'Wuthering Waves', and 'Zenless Zone Zero'. Since the rest of the list has remained fairly stagnant, these titles stood out with climbs of three to four places. Each of these games saw a spike in search volume driven by update news. 'Lord Nine' is particularly noteworthy for its return to the Top 10, and it will be interesting to see if it can maintain the momentum to solidify its spot.

Online – PoE 2 Nearing a Top 10 Breakthrough

The Top 10 list remains unchanged from last week. From the number one spot held by 'League of Legends' down to 'The Great Merchant' at number ten, the rankings—and even the search volumes—are virtually identical to the first week of September. This 'frozen' state in the online game category is becoming a recurring phenomenon that no longer surprises us.

However, it is worth noting the titles looking to break this silence. 'Path of Exile 2' is the standout, climbing four spots this week to take 11th place, putting it right on the doorstep of the Top 10. It is currently the most dynamic title in the online gaming sector.

The prospect of entering the Top 10 is quite realistic. The gap between it and The Great Merchant is roughly 10%, and given the current buzz around Path of Exile 2, one can certainly be optimistic. After a sensational start in early access, interest had waned, making this current resurgence a welcome sight. Let’s see if it hits the mark next week.

Another title showing promise is 'World of Warcraft', which now sits at 22nd. It is climbing the ladder quietly and consistently. Following the reveal of the 11th expansion’s cinematic trailer at Gamescom, the steady drip of new content information seems to be driving the uptick in search volume.

Steam – Hollow Knight: Silksong Debuts, Immediately Rivaling PUBG

Following the fiery debut of 'Super Robot Wars Y' last week, the second week of September has brought another rookie that demands attention. The impact is even greater than last week: it is 'Hollow Knight: Silksong' (hereinafter Silksong). A title that has had players on the edge of their seats from its very first announcement through every delay and surprise reveal.

Silksong has made a staggering debut, landing straight at second place on the Steam chart. More importantly, it isn't just sitting in second; it is nipping at the heels of the long-standing leader, 'PUBG'. Silksong’s early performance is immense. Since its official launch on September 4th, it topped the Steam Global Top Sellers list and surpassed 530,000 Concurrent Players, finally letting all that pent-up anticipation explode. Content related to the game is flooding the web.

Additionally, the arrival of the sequel has given the original 'Hollow Knight' a boost, seeing it climb the charts as well. It seems players have been spending their time with the original to prepare for the new release. In fact, since the surprise announcement of the release date in August, the Concurrent Players for Hollow Knight on Steam steadily climbed to hit 95,000. While those numbers have dipped from the peak, it serves as a testament to the powerful influence of a new series entry.

Pre-registration – The September Schedule Takes Shape

The September release schedule is finally coming into focus. As mentioned in the mobile game chart, The Starlight, Goddess Order, and Aetheria: Restart will launch sequentially on September 18, September 24, and September 25, respectively. Furthermore, 'Starlight', which took 7th place in pre-registrations this week, officially launched on September 10.

On top of this, Dream Age will hold an online showcase for its new title, 'Architect: Land of Exile', on September 17. The developers plan to share a host of information while simultaneously opening pre-registrations. It is yet another highly anticipated title revving its engine, and we are keen to see where it goes from here.
