The sweltering heat has officially arrived. For any self-respecting gamer, the true way to escape the summer is to hide under the air-con and scavenge the Steam storefront. One of the best ways to unearth a hidden gem is the 'tag' system. Steam tags aren't just mere genre labels; they are a massive recommendation engine forged by the collective intelligence of the community. When developers and players slap tags—be it genre, system, graphics, story, or subject matter—onto a game, you can simply click through to find titles that match your specific taste.

Yet, where there is light, there is shadow. While popular tags dominate the storefront, there are unpopular ones gathering dust in the corners of the search bar. Although Valve has recently purged a mountain of subjective and vague tags, the ones listed here possess such a distinct identity that deleting them feels like a mistake. Still, they remain like 'chicken ribs'—hard to discard, yet hardly anyone is looking for them. Let’s dive into the abyss of the Steam store and drag out the bottom five.

In fifth place is 'Volleyball,' claimed by a measly 43 games. In a sports gaming market where football and basketball rake in cash by the shovel every year, volleyball is treated like an unwanted guest. The biggest culprit is the rule that you cannot hold the ball. From a player’s perspective, there’s no satisfying 'grip' on the ball; you’re just desperately tapping buttons to hit at the right moment based on the landing spot. The rigid 'receive, toss, spike' loop also heavily restricts gameplay freedom.

Camera angles are another headache for developers. A vertical view distorts depth perception, while a side view tangles up your character controls. Plus, you’re expected to choreograph complex blocking and coverage with AI teammates in a cramped court? It’s a development nightmare with a tiny audience—hardly a cost-effective venture. It’s telling that the most famous volleyball game in Korea is 'Pikachu Volleyball.' The struggle of this unpopular genre is dripping from its Steam tag.

Fourth place goes to 'Rugby' with a mere 37 tags. Rugby is another uncharted wasteland in the sports game market. Compared to 'Madden NFL,' which devours the North American market, the pathetic state of rugby games is painful. Rugby matches are long with continuous play and endless 'ruck' or 'maul' situations where players pile on top of each other. For a developer, building a physics engine that doesn't look like a glitchy mess while dozens of hulking players collide is basically a disaster.

Commercial reasons also keep publishers’ wallets firmly shut. While rugby is practically a national religion in the UK or Australia, it remains a niche sport in massive markets like the US, China, Japan, and Korea. Since it doesn’t click in major regions, global publishers see no reason to dump tens of millions of dollars into development. To make matters worse, licensing is fragmented across various unions, causing giants like EA to walk away early. Even the few developers who do make rugby games prefer stuffing their titles with popular tags like 'Sports' rather than the 'Rugby' tag that nobody searches for anyway. It’s destined to suffer forever.

Third place is the 'Zoo' tag, found on only 33 games. Despite a magnificent lineage starting with the 'Zoo Tycoon' series and continuing to 'Planet Zoo,' the popularity of this tag is abysmal. If you search 'Zoo' on Steam, hundreds of games and DLCs flood the screen, yet only a tenth of them actually wear the 'Zoo' tag like a badge of honour. Even though it’s a staple subject in simulation, developers seem to feel no need to apply such a specific tag.

In reality, many zoo-themed games skip the 'Zoo' tag in favor of high-traffic keywords like 'Management,' 'Sandbox,' or 'City Builder.' Moreover, just because a game features animals doesn't mean it’s a zoo game—some are set in the wild or national parks. Consequently, there’s no real reason for people to search for 'Zoo' games. In the end, the 'Zoo' tag has become an endangered species, wandering the outskirts without ever being absorbed into a major category.

Second place is the somewhat unfamiliar 'Snooker,' registered to 29 games. Snooker is a type of cue sport that originated in British India in the late 19th century; it's quite different from the 3-ball or 4-ball billiards popular in Korea, or pool. The table is larger than a standard one, and it uses 22 balls. It’s a repetitive game of pocketing a red ball, then a colored ball. While it’s considered a major cue sport globally—especially in Commonwealth nations—in Korea, it’s rare to even find a dedicated table.

However, it’s bound to be unpopular in gaming. The reason is its sheer difficulty. Billiards is supposed to be fun even if you get a 'lucky shot,' but in snooker, the table is massive, the balls are small, and there are so many of them that just navigating around obstacles is a chore. With the broader 'Billiards' tag already sitting there, it’s only natural that fewer games opt for the 'Snooker' tag. With so few creators and so few digital players, it’s a doomed tag that has sunk into the deep sea.

The grand prize for the most unpopular tag goes to 'Reboot,' chosen by a mere 19 games. A reboot is like restarting a computer; it’s a franchise's life-support system that wipes the slate clean of tangled lore and settings. It offers old fans a fresh take on a familiar IP, while sending a message to newbies that it’s the perfect time to jump in. Masterpieces like Crystal Dynamics' 'Tomb Raider' or Firaxis Games' 'XCOM' are successful examples that carry this tag.

So why is this the number one unpopular tag? Because the requirements to earn it are incredibly steep. First, you need an existing IP with a decent level of recognition, but there must be some reason why the series can no longer continue in its current state. Then, the developer must choose the path of a reboot rather than a remake or remaster, which adds the burden of pouring in massive development resources. How many companies or IPs can afford to make such a bold decision? Because of the weight the 'Reboot' tag carries, it’s unlikely to disappear, but it remains the rarest item in the Steam store—a tag that almost no one can actually use.
