‘KookminTree’s big data game rankings for the fifth week of October 2025 are here. KookminTree tracks search trends from major portals every week to bring you the pulse of the gaming world. Let’s dive into what everyone’s been searching for lately.

Mobile – Two Newcomers Crash the Top 10

Welcome to our weekly big data breakdown for the final week of October 2025. Two titles that launched simultaneously on October 22nd have sent shockwaves through the mobile charts, both landing straight into the Top 10. The culprits? DreamAge’s 'Architect: Land of Exile' (hereafter 'Architect') and Smilegate’s 'Chaos Zero Nightmare' (hereafter 'Kazenah').

Architect stormed the charts at 3rd place, which, given the sheer congestion of the top 10 these days, is nothing short of impressive. Most notably, it managed to knock the genre’s seasoned titan, 'Lineage M', down a peg—a feat that has certainly turned some heads.

Developed by Park Beom-jin’s squad at Aqua Tree—the folks behind 'Lineage 2 Revolution' and 'Ni no Kuni: Cross Worlds'—it’s built on Unreal Engine 5 to deliver a sprawling, single-channel seamless open world. With search volume and platform rankings looking healthy, it seems poised to keep this momentum going for a while.

Kazenah, meanwhile, is turning heads with its blend of roguelike, deck-building, and mobile subculture vibes. It’s a global one-build release spanning 174 countries across mobile and PC. The core hook is raising characters in an intriguing world and clearing stages with custom decks. While it built up a decent following before launch, the devs now face the urgent task of putting out fires regarding its story and live service operations.

Beyond the headliners, October has been a busy month for new releases. Titles like 'Wadada Dungeon Run', 'Astellia M' (12th, +1), 'Stella Sora' (21st, NEW), and 'Tian Di Jie' (39th, NEW) are making waves. It feels like the new-game fever that dominated Steam in Q3 has officially bled into the mobile sector. It’ll be fascinating to see how this chaos reshapes the charts in the coming weeks.

Meanwhile, we’ve got a shuffle at the top. With 'Mabinogi Mobile' showing signs of fatigue at second, 'Roblox' has seized the throne. However, this shift wasn't driven by a massive spike in Roblox searches, so if Mabinogi Mobile finds its footing, we might see the crown change hands again soon.

Online – Lost Ark Returns to the Top 10

'League of Legends' continues to see its search volume skyrocket, likely fueled by the ongoing 2025 LoL World Championship. With the quarterfinals kicking off on October 28th and the competition heating up as semifinalists are decided, expect this upward trend to hold steady as long as the tournament lasts.

On a brighter note, 'Lost Ark'—which caused quite a stir by dropping out of the Top 10 last week—has made a swift return. It’s climbed two spots to 9th. It wasn’t a massive explosion of interest, but it’s a sign that their consistent updates and player communication are finally paying off.

However, the developers shouldn't get too comfortable. With 10th-place 'The Great Merchant' and 11th-place 'Diablo 4' breathing down its neck, Lost Ark needs some fresh fuel to stabilize its position and hopefully climb back to its former glory.

Elsewhere, 'LaTale' and 'Path of Exile' both jumped two spots, while 'Diablo 4' slipped out of the Top 10. 'Cyphers' (15th, -1) and 'Path of Exile 2' (18th, -1) also saw some turbulence. Notably, 'The Great Merchant' dropped three spots, leaving us wondering if they have a comeback card up their sleeve.

Steam – The Terrifying Pace of the Duck

The star of this week’s Steam chart is undoubtedly a 'duck'. We’ve seen plenty of duck-themed games before, but this one hits differently. I’m talking about 'Escape from Duckov' (hereafter 'Duckov'), a fresh release from October 16th that has already sold a million copies in just one week.

Duckov markets itself as an extraction shooter with a lighter touch—dialing back the PvP intensity while keeping the strategic tension of extraction and resource management intact. That balance has clearly struck a chord with players worldwide.

Throw in some adorable character designs, deep customization, and various progression systems, and you get a title currently sitting on 'Very Positive' reviews on Steam. It debuted at 4th in our big data rankings, holding its own against some heavy hitters. Watching how far Duckov can soar in such a competitive space will be quite the spectacle.

Last week’s mention, 'Sheng Shi Tian Xia: Birth of the Empress', climbed two spots to break into the Top 3. Alongside Duckov, it’s been a major player this week, proving that even 'watchable' games can exert massive influence. The Steam charts are currently a haven for fresh genres and unique mechanics, and I, for one, can’t wait to see which game takes the baton next.

Pre-registration – RPGs Still Rule the Roost

The pre-registration charts are, predictably, an RPG-heavy affair. Aside from a few outliers, it’s mostly role-playing games, largely because it’s the easiest genre to generate pre-launch search volume and slap the 'blockbuster' label onto. Still, with titles like 'Dragon Flight 2' and various collection/idle games carving out a niche, it’s not a total monopoly. Here’s hoping we see a wider variety of genres gearing up for launch soon.
