NCSoft’s free-to-play MMORPG AION 2 went live worldwide on October 5, 2026, and within hours it had done something few PC releases manage this year: it cracked 300,000 concurrent players on Steam alone. By the evening of launch day, SteamDB logged an all-time peak of 397,905 concurrent players, a number that puts AION 2 ahead of several AAA 2026 releases and makes it, by most counts, the fourth most-played new game of the year on Valve’s platform.

But the launch tells two stories at once. The player count is a genuine win for NCSoft, a Korean publisher that has spent years trying to prove it can build something beyond its aging Lineage cash cow. The Steam user-review score, sitting at a “Mixed” 66 percent positive, tells a messier story about generative AI in game development, aggressive monetization, and what happens when a beloved 2008 MMO gets rebuilt for a 2026 audience that has learned to be suspicious of both.

AION 2’s Launch Numbers, By the Hour

The rollout happened in two stages. NCSoft opened early access on September 30, 2026, exclusively for players who bought a Founder’s Pack. That paid tier alone pushed concurrent Steam players past 171,530, according to TheGamer and Inven Global. During that early-access window, AION 2 also ranked first in Steam sales across 12 countries, including the United States, France, Germany, Spain, and Brazil.

Then came the free global launch on October 5. With the paywall gone, the concurrent count more than doubled, hitting an all-time Steam peak of 397,905 within a few hours, per Enduins and corroborated by SteamDB’s own tracking page for the title. NCSoft itself claims the real number is higher once its proprietary PURPLE launcher is factored in, putting combined concurrency above 400,000 players. SteamDB only counts Steam clients, so the PURPLE figure is NCSoft’s own claim and hasn’t been independently verified the way the Steam number has.

Those numbers put AION 2 in rare company. According to TheGamer’s reporting, the launch-day surge pushed the game past Resident Evil Requiem, Meccha Chameleon, and Forza Horizon 6 in concurrent Steam players, making AION 2 the fourth-most-played 2026 release, trailing only Task Bar Hero, Subnautica 2, and Wardogs. For a subscription-free MMORPG with no console release and no marquee single-player campaign, that’s a genuinely unusual outcome, and it’s why AION 2 is suddenly a bigger talking point than most October 2026 game launches.

What Is AION 2, and Who Made It?

AION 2 is NCSoft’s attempt to revive the AION brand, which launched its original game back in 2008 as a subscription MMORPG built around faction warfare between winged Daeva and a contested sky realm. The sequel keeps the core pitch, factions fighting over airborne territory, Daeva transformation, PvP-driven world conflict, but rebuilds it as a modern free-to-play title running on Steam and NCSoft’s own PURPLE PC platform. There is no PlayStation, Xbox, or Switch 2 version confirmed at this point. AION 2 is a PC-only release for now.

NCSoft didn’t launch AION 2 everywhere at once. The game actually debuted first in South Korea and Taiwan back in November 2025, where it reportedly crossed ₩100 billion in cumulative sales within 46 days and generated ₩136.8 billion in first-quarter 2026 revenue in those markets. October 5’s rollout was the delayed push into North America, Europe, and the rest of Asia, the markets that matter most for proving AION 2 can be more than a regional hit.

That global expansion matters strategically. NCSoft has leaned on its Lineage franchise for the bulk of its revenue for two decades, and a successful AION 2 launch in Western markets is the clearest sign yet that the company can build a second pillar. It’s a similar playbook to what Jagex is attempting with its own engine overhaul, detailed in shattered.io’s coverage of RuneScape’s RS4 relaunch, where an aging MMO brand gets a full technical rebuild to chase a new generation of players.

The AI Controversy Behind the 66% Score

Here’s where the story gets complicated. AION 2’s Steam user reviews currently sit at a “Mixed” 66 percent positive rating, according to TheGamer’s launch coverage, a soft score for a game pulling in 400,000 concurrent players. The friction isn’t really about bugs or server stability. It’s about how the game was made and how it monetizes.

NCSoft built AION 2 using its own generative AI toolchain, internally called VARCO, which the studio has used to generate text, art assets, and audio, and to help run QA checks during development. NCSoft hasn’t published a detailed breakdown of exactly how much of the game VARCO touched, but the company’s own Steam store listing for AION 2 states plainly that “some in-game assets were created with the assistance of AI tools” and that “Arcana card designs and some icons use AI-generated assets,” language TheGamer flagged directly from NCSoft’s own product page. Players have also pointed out that AION 2’s key art looks visibly AI-generated.

That disclosure, small as it looks on a store page, landed in a review environment that’s already primed to punish AI-assisted art. The backlash echoes a pattern shattered.io has tracked elsewhere this year, including the uneven reception to Control Resonant’s launch review scores and the negative-review spike around Witcher 3 Remastered, where a vocal review-bombing minority can drag down an otherwise commercially successful launch.

Monetization Is the Bigger Complaint

According to TheGamer’s review of the Steam feedback, AI isn’t actually the top complaint, monetization is. Multiple negative reviews cited in that coverage describe AION 2 as a game “designed and built around its monetization, not the player,” with reviewers walking through specific cash-shop mechanics they consider aggressive for a title that already sells paid Founder’s Packs on top of its free download.

One frustrated reviewer, who described themselves as a veteran of the original 2008 AION on both official and private servers, argued the sequel “has absolutely nothing to do with the first game anymore” and predicted it would drift toward pay-to-win mechanics over time. That sentiment, fair or not, is a familiar one in the MMORPG genre right now. shattered.io’s breakdown of Genshin Impact’s pay-to-win math and the ongoing debate over whether gacha RNG is provably fair both show how quickly player goodwill evaporates once a free-to-play title’s monetization becomes the main topic of conversation instead of its gameplay.

AION 2 vs. Throne and Liberty: NCSoft’s Own Benchmark

The most useful comparison for AION 2 isn’t a competitor’s game, it’s NCSoft’s own last big Western MMORPG swing. Throne and Liberty launched into early access in 2024 and peaked at 56,910 concurrent Steam players during that window, per data reported by Chosun Ilbo. AION 2’s early-access peak of 171,530 is roughly three times that figure, and its full-launch peak of 397,905 is nearly seven times larger.

SteamDB and NCSoft haven’t published exact figures for the three 2026 titles that still out-rank AION 2 in peak concurrency, Task Bar Hero, Subnautica 2, and Wardogs, so a precise gap can’t be calculated yet. What’s clear is that AION 2 has already outpaced every other MMORPG NCSoft has shipped into the Western market this decade, and it did so without a single console SKU.

NCSoft’s Stock and the Market Reaction

Investors noticed the early-access numbers before the free launch even happened. NCSoft shares reportedly climbed more than 14 percent over the two trading days following the September 30 early-access start, closing at ₩244,500 on October 2, according to Chosun Ilbo’s market coverage. A specific share-price move tied directly to the October 5 global launch hasn’t been confirmed in available reporting, but the early-access rally alone signals that investors are treating AION 2 as a legitimate second growth engine alongside Lineage.

That reaction lines up with how markets have treated other big platform and hardware launches this year. shattered.io’s coverage of Steam’s record-setting $1.7 billion September showed that the PC gaming platform as a whole is on pace for a $20 billion year, and a single breakout MMORPG launch like AION 2 is exactly the kind of event that can pull a chunk of that spending toward one publisher.

Historical Context: The Original AION’s Long Shadow

The original AION launched in 2008 as a subscription-based MMORPG and built a loyal, if shrinking, player base over the following decade and a half. It never reached the cultural footprint of World of Warcraft or the regional dominance of Lineage, but it carved out a distinct identity around faction war and flight-based combat that’s rare in the genre. AION 2 leans hard into nostalgia for that identity while swapping the subscription model for free-to-play, a shift that mirrors nearly every surviving MMORPG from that era, including Lineage itself.

The tension in the Steam reviews, between players who feel AION 2 honors the original and those who feel it has nothing to do with the first game, is really a tension about what a 2008 MMO is allowed to become in 2026. NCSoft bet that a bigger, free, AI-assisted, cash-shop-driven AION would draw a bigger audience than a faithful subscription sequel. The player numbers suggest that bet worked. The review score suggests not everyone is happy about how it worked.

How AION 2 Stacks Up Against the Broader MMORPG Field

The pattern here isn’t unique to AION 2. Free-to-play MMORPGs increasingly win the concurrency race while losing the review-score race, because the mechanics that drive the biggest player spikes, aggressive marketing, Founder’s Pack tiers, cash-shop systems, are often the same mechanics that generate the harshest user reviews once the honeymoon period ends. shattered.io has tracked similar monetization scrutiny across mobile gaming’s $6.57 billion market, where download numbers and revenue keep climbing even as player sentiment around monetization gets more skeptical by the year.

The Generative AI Question Isn’t Going Away

AION 2 is one of the first major MMORPG launches to put a generative AI disclosure directly on its Steam store page, and the reaction suggests publishers haven’t figured out how to message that disclosure without triggering backlash. NCSoft’s VARCO framework reportedly touches text generation, art assets, audio, and QA tooling, but the company hasn’t broken down exactly which parts of AION 2 relied on it versus traditional development. That ambiguity is arguably doing more reputational damage than a fuller disclosure would, since players are left to assume the worst about how much of the game’s art and writing is AI-generated.

Expect this to become a template fight for the rest of the decade. As more studios adopt internal AI tooling to compress production timelines, the Steam store disclosure requirement, paired with a review culture that treats “AI-generated” as a red flag regardless of degree, means every AI-assisted launch is going to face some version of the scrutiny AION 2 is facing now.

Competitive Landscape: Where AION 2 Fits

AION 2 isn’t competing in a vacuum. Lost Ark, World of Warcraft, and NCSoft’s own Throne and Liberty all occupy overlapping space in the Western MMORPG market, and none of them launched with anywhere near AION 2’s opening concurrency. That said, concurrent-player peaks are a notoriously poor predictor of long-term retention. MMORPGs live or die on how many players are still logging in three months after launch, not how many showed up on day one. NCSoft’s own history with Throne and Liberty, which saw a strong early-access peak followed by a steadier, smaller sustained population, is the most relevant precedent for what AION 2’s player count will likely look like by early 2027.

The other competitive wrinkle is platform strategy. By skipping consoles entirely, NCSoft is betting that AION 2’s audience is concentrated enough on PC, through Steam and its own PURPLE launcher, that it doesn’t need a PlayStation or Xbox release to hit scale. That’s a different bet than most big 2026 MMO launches are making, and it will be worth watching whether NCSoft eventually reverses course the way other PC-first MMORPGs have.

What Happens Next for AION 2 and NCSoft

A few things are worth watching over the next few months. First, whether the 66 percent Mixed review score recovers as the initial AI and monetization backlash settles, something that happened with other review-bombed launches once content updates and balance patches shipped. Second, whether NCSoft publishes a fuller breakdown of VARCO’s role in development, which could either defuse or reignite the AI controversy depending on what it reveals. Third, whether the Steam concurrency number holds up past the first month, since early-access and launch-week spikes routinely fall by 50 percent or more within the first 90 days for MMORPGs. Fourth, whether NCSoft’s stock gains from the early-access rally hold once a full quarter of global revenue data is available. And fifth, whether AION 2’s console-free strategy changes, given how much of the broader gaming market has shifted toward PC/console parity for major live-service titles.

What’s not in question is that NCSoft now has clear proof its second major Western MMORPG swing landed harder than its first. Whether that translates into a durable live-service hit instead of a loud launch week is the question that will define AION 2’s next six months.
