From high-fashion and quirky characters to confectionery, everyone seems to be scrambling to collaborate with baseball clubs to woo the fans. It is the shifting nature of the fandom that is really steering this ship. The consensus is that the KBO fanbase has undergone a radical transformation since the pandemic. Driven by the regional loyalty system, the demographic has broadened significantly. With families and friends now flocking to stadiums for the communal experience and the myriad of event zones, the sheer influx of new interest has been undeniable.

The numbers speak for themselves: 2024 was declared the '10 million spectator era,' and this year, the league hit the '8 million spectator' mark in just 465 games, setting a record pace. As the crowds swell, related traffic and merchandise sales have naturally skyrocketed. Industry insiders attribute this to the consumption habits of fans in their 20s and 30s. It’s the age of values-based consumption, where savvy platform usage amplifies the indirect marketing ripple effect.

This trend is backed by hard data from pop-up stores at venues like Hyundai Department Store and various convenience store chains that have stocked collaborative goods. With industries across the board eyeing the KBO, gaming companies are also jumping into the fray to bolster their bottom line and polish their brand image.

Baseball collaborations often stumble because they are typically signed with individual clubs rather than the league as a whole. This is largely because the parent companies of these clubs have their own rivalries to navigate. Take, for instance, the launch of local 'Haitai Homerun Ball' editions or the Samlip 'KBO Bread' line—Lotte Giants products were conspicuously absent. Similarly, when CASETiFY released their KBO phone cases, the Samsung Lions design was limited to the 'Samsung Galaxy' version.

Gaming companies face the same hurdles. You will rarely see NC Dinos content integrated into games from rival publishers. Instead, NCSoft keeps its promotional efforts in-house, distributing merchandise and items within its own games or hosting content directly at the stadium. They famously distributed 'Dandi' mascot costumes and uniforms during their founding days, and the sight of their 'Execution Sword' being hoisted at the center of the field during their 2020 championship season remains legendary.

Furthermore, they have consistently used game-themed uniforms during the season to drive sales. Their recent collaboration with the character IP 'Doguri' has been a masterclass in aggressive, omni-channel marketing. The result? The 2025 Doguri fashion uniforms sold out in every size, and their authentic jerseys followed suit, leaving only the smallest sizes behind. It is a textbook case of leveraging internal IP to secure revenue and burnish a corporate image.

So, how are other developers tackling the baseball crowd? Let’s look at Com2uS, which holds official KBO license agreements and has a stable of baseball titles. Having started with feature phones, they have been a mainstay in KBO offline marketing for years. They continue this strategy today, blanketing stadiums with promotional material regardless of whether it is a regular season game or an exhibition match.

By stepping up as title sponsors for event matches, Com2uS has secured the highest brand awareness among domestic baseball game developers. Online, they are just as savvy, leveraging video content through partnerships between their game models and the clubs those models represent. By showing players actually engaging with their games, they are effectively capturing potential customers. This relentless marketing push has paid off, with Com2uS seeing a steady rise in baseball game revenue since 2022. As of May, they reported a 3.0% increase in separate revenue for their gaming division in Q1, fueled by the overall strength of their baseball titles.

Nexon took a different route, partnering with KT WIZ for a 'MapleStory IP Brand Day.' True to its name, the stadium in Suwon was transformed into a MapleStory wonderland, complete with Pink Bean characters everywhere. The event featured thematic photo zones, a first-pitch by Pink Bean, and a special pop-up store. During the game, players even wore collaboration uniforms, and the stadium’s big screen displayed custom animations featuring Pink Bean and Orange Mushroom.

According to Nexon, the event was designed to bridge the gap between in-game memories and real-world experiences for a game that has now entered its 22nd year. A Nexon official noted, "We are deeply grateful to the many users and spectators who responded so well to the meeting of baseball’s daily joy and the world of MapleStory, creating moments of fun and emotion together." The turnout was massive, and both the IP holder and the club walked away with healthy gains from merchandise and uniform sales.

Now, even global gaming firms are muscling in on the KBO action. Supercell partnered with the Doosan Bears for 'Brawl Stars,' targeting the lucrative Children's Day crowd. They set up photo zones with Brawl Stars characters decked out in Doosan uniforms and hosted pop-up stores that had families opening their wallets with ease. Following the success of this event, the two sides have already promised a water party in August, complete with water cannons and guns. Supercell also donated all proceeds from the event, killing two birds with one stone: acquiring new users and fulfilling their ESG responsibilities.

The Pokémon IP, which has been working closely with Lotte affiliates since last year, has also been a constant presence at the ballpark. In May, they launched themed merchandise—headlined by Pikachu uniforms—and operated a Pikachu-themed pop-up store at the Busan Sajik Baseball Stadium. On Children's Day, they even staged a parade of Pikachus in various Lotte Giants uniforms, creating a spectacle for the fans.

In June, they took it a step further with a Pokémon GO collaboration, bringing the digital experience into the physical realm. A Pokémon GO booth was set up in front of the stadium, and they handed out Pikachu sun visors and cheer sticks to fans. They also created a real-world replica of an in-game PokéStop, giving fans plenty to photograph.

In-game, they boosted spawn rates for popular and shiny Pokémon around the Sajik stadium and offered a special Pikachu themed with the stadium's location. Niantic reported that over the three days of the event, roughly 10,000 visitors collected merchandise, and the onsite event saw an estimated 60,000 impressions.

When onsite events aren't feasible, gaming companies are integrating KBO content directly into their games, often including as many clubs as possible to maximize appeal. WeMade, for instance, introduced mascots from various clubs wearing their respective uniforms into 'Legend of Ymir.' These mascots function as 'Disir' (pets), acting as partners and helpers for players.

Pearl Abyss also joined the party on the 22nd, launching KBO-themed costumes in Black Desert Mobile. Excluding the NC Dinos and Doosan Bears, they released 'Home and Away' uniforms for eight clubs. Instead of the usual player names and numbers on the back, they cleverly featured the number of seasons each club has won, highlighting their history. It hits the mark for the modern fan's desire for value-based consumption and the joy of owning 'limited edition' goods, giving players a new way to showcase their team pride in-game.
