Numbers have always been a key foundation when discussing a game's popularity. In domestic online games, PC cafe market share was the familiar metric for measuring success, while for packaged games, it was sales volume. Beside these figures—which remain in use today—Steam concurrent player counts have established themselves as a core benchmark. When a new title releases, people check its peak CCU (concurrent users), and when an active game's player base rises or falls, they examine the charts. Few data sources reflect player response as quickly as these frequently updated figures.
Behind this trend lies Steam's expanded scale and influence in the gaming market. As Inven reported on October 13, Steam broke its all-time record on October 11 (UTC) with 43,505,724 concurrent online users. On that day, the number of users actively playing a game also reached approximately 14.46 million.
Steam's importance is also evident in how game publishers distribute and promote their titles. Ubisoft announced a return to day-one Steam releases for its 2024 games and launched 'Assassin's Creed Shadows' on Steam on day one last year. According to Valve's 2025 year-in-review, developers posted 436,592 game updates on Steam, generating 3.13 billion user views. Steam has grown into a massive platform not just for purchasing and playing games, but also as a hub for staying informed on news.
The game-by-game concurrent user graphs published by such a massive platform serve as a convenient clue for gauging success. But if a chart registers 170,000 players, can we really assume that 170,000 people logged on to actually play that game?
170,000 Players Gathered in a Game That Usually Had Dozens
'UBERMOSH:OMEGA' is a single-player top-down shooter released in 2019. According to SteamCharts data, its peak concurrent player count last September reached only 37. Yet on October 12, its peak concurrent user count on SteamDB suddenly surged to 174,886.
Japanese gaming outlet AUTOMATON pointed out that the surge in concurrent players coincided with the recent addition of Steam Trading Cards to the game. Noting that other titles in the same franchise saw player spikes following the addition of cards, the outlet raised the possibility that automated accounts (bots) meant for farming trading cards had flooded in.
Steam Trading Cards are dropped periodically as play time accumulates in supported games, regardless of achievement unlocks. The amount obtainable through gameplay is usually about half of a full set. Players can trade them with others or buy and sell them on the Community Market, and completing a set rewards badges and profile customization items. Selling cards grants Steam Wallet funds.
Because cards can be sold on the marketplace, there is an incentive to run the game across multiple accounts to farm them. Furthermore, most of these cards drop simply by accumulating play time. As a result, bot accounts left idle in the game became the primary driver inflating the concurrent player count. The public figures provide no data distinguishing between accounts actively playing the game and those merely kept running for card collecting. Consequently, when card farmers deploy accounts en masse, 'UBERMOSH' appearing out of nowhere on the charts as a popular game inevitably looks bizarre to observers.
A Problem Valve Knew About, Spikes Repeated
Valve addressed this problem back in 2017 when altering its policy system. This was during a period when certain developers generated game keys in bulk, distributed them to bot accounts, and profited by collecting cards. At the time, Valve highlighted the risk that bot-generated activity could trick store algorithms into misidentifying the game as genuinely popular among actual users.
The countermeasure was changing the policy of granting cards immediately upon a game's release. Instead, Valve allowed card drops only for games that established confidence through actual user purchases and engagement. Current Steam developer documentation also outlines sales and user engagement as criteria for trading card eligibility. This established a mechanism to filter out games created solely for trading card profits.
Yet incidents like this have continued to occur ever since. In 2018, 'Geneshift' (now 'Skillshot City') saw its concurrent player count surge to the 210,000 range during a free giveaway event. In an official announcement, the developer highlighted flaws in Valve's card system, stating that over 200,000 bots were idling in the game to farm cards. The developer noted that Reddit promotions had brought in thousands of real new players as well; while the event succeeded in promoting the game, the figure on the charts was vastly exaggerated by card-farming accounts.
An even larger spike occurred in 2021 with 'Capcom Arcade Stadium'. Its concurrent player count skyrocketed from 18 to over 480,000 in about 10 hours. US tech outlet Ars Technica pointed out that trading cards were being dropped even for free users, naming card-farming bots as the likely cause.
In July of this year, 'Artifact Classic'—which usually averages anywhere from dozens to a few hundred concurrent players—surged to the 10,000 mark without any notable update or promotion. Inven reported on suspicions of bots or artificial CCU inflation at the time. Thus, doubts regarding the gap between popularity shown on CCU graphs and actual gameplay continue to surface even with older games.
Is a Game a Failure When CCU Drops?
The opposite scenario unfolds when player counts drop. In January 2023, when Steam concurrent players for the global service of 'Lost Ark' plummeted, publisher Amazon Games officially explained that it was the direct result of a massive bot account ban wave.
Lost Ark's bots disrupted the in-game economy and player environment by farming and selling gold. At the time, the operating team expected the reduction in bots to improve the trading experience in the marketplace and auction house, as well as reduce latency in crowded zones. The chart decline was a shift resulting from purging malicious accounts. Although this significantly reduced the concurrent player count for Lost Ark's global service, it allowed actual in-game users to enjoy a smoother gaming experience than before.
Interpreting a drop in concurrent players immediately as player churn or commercial failure misjudges actions taken to create a healthier gameplay environment. The reasons behind a decrease in numbers are just as important as those behind an increase.
A game's design structure also impacts CCU. Single-player games that players finish and put down vs. online games that keep players logged in daily for long sessions can yield vastly different graphs even with identical total player counts. For games with substantial player bases on consoles or other PC launchers, the audience outside of Steam must also be considered. Ultimately, Steam's concurrent player count cannot serve as an absolute metric.
What Should We Look at Beyond Concurrent Players?
The issue demonstrated by these cases is clear. Concurrent player graphs swing dramatically based purely on fluctuations in automated accounts. Reading those numbers as commercial success requires corroborating evidence regarding actual purchases and gameplay.
First, it is necessary to examine player retention trends following a peak record. This means observing whether player activity persists days or weeks later, and how many players remain after updates or sale events end. UBERMOSH reached over 170,000 concurrent players on October 12, but SteamCharts observations the following day dropped back down to the thousands range. Judging a game solely by its peak misses this essential element of player engagement longevity.
To gauge commercial success, sales volume and revenue must be checked alongside CCU. Sales figures published by developers or Steam's weekly top sellers lists provide that evidence. Steam's 'Top Sellers' chart reflects not only base game sales, but also DLC and in-game microtransactions. If purchasing performance rose during a period of increased activity, it supports the claim that genuine consumer spending demand existed.
The true picture of active engagement emerges from examining specific gameplay experiences shared in reviews and community discussions. This involves checking whether strategy guides for new content are being shared, which combat mechanics or systems players enjoy, and why players choose to quit. Such feedback explains why people continue playing or walk away, while offering readers valuable insight to determine if a game fits their personal tastes.
CCU trends show how long player engagement lasts, sales volume and revenue demonstrate commercial performance, and detailed reviews reveal why players seek out a game. When distinct data points align in the same direction, the conclusion of genuine success gains real weight. While concurrent user counts offer a highly intuitive and accessible metric, relying solely on CCU figures to judge a game's popularity is clearly incomplete.
