Nexon: give the game away, sell what's inside — Korea's free-to-play pioneer

In the 1990s video games were boxed software or hourly dial-up services, and Korean players — like everyone — paid upfront for a product they might hate. Kim Jung-ju, a KAIST graduate student, founded Nexon in 1994 and launched The Kingdom of the Winds in 1996, widely credited as the world's first graphic MMORPG. An online world with no box to sell needed an entirely new way to make money.

Let everyone play free, then sell the things players want inside — items, looks, speed. The game becomes the venue; desire becomes the price tag.

Nexon opened the game to everyone and made money by selling virtual items to the players who wanted them. The loop was refined across hits like MapleStory's cash shop and KartRider — a free racing game whose karts and items carried the revenue. Western analysts dismissed it as an Asian curiosity, but Nexon's model scaled across Asia: by 2011 the company went public on the Tokyo Stock Exchange in Japan's largest IPO of that year.

Nexon proved, years before the West believed it, that people would pay real money for virtual goods — sales passed 1 trillion won the year of its IPO, making it the first Korean gaming company to do so, while the U.S. virtual-goods market alone topped $2 billion in 2011. Free-to-play went on to become gaming's dominant business model, from mobile hits to Fortnite.

Kim Jung-ju started Nexon in 1994 as a KAIST doctoral student, and in April 1996 launched The Kingdom of the Winds, generally credited as the world's first graphic MMORPG. The hard question was commercial: an always-online world had no shrink-wrapped box, and Korean gamers of the era were hardly a captive market for subscriptions. Nexon's answer inverted the industry's logic — admission free, merchandise priced.

Players could spend nothing and still play, but the things that made a character distinctive or strong — items, appearances, conveniences — cost real money. Because virtual items cost nothing to duplicate, every sale was nearly pure margin, and because payment attached to desire rather than access, willing spenders could subsidize millions who never paid. Nexon carried the model through MapleStory's cash shop and KartRider, a Mario Kart-style racer that was free to download and earned its keep selling karts and gear.

The model's vindication was financial. When Nexon listed on the Tokyo Stock Exchange on December 14, 2011, it was Japan's largest IPO of the year, and the company became the first Korean game maker to book more than 1 trillion won in annual sales. Commentators noted the deeper significance: in an era when many doubted anyone would buy intangible goods online, Nexon had demonstrated that people pay for bits — a finding that now underwrites most of the games industry.

Free entry removed the biggest funnel-killer — paying upfront for an unknown world — so the player base grew to market scale before a won changed hands.

Pricing attached to desire rather than access: cosmetic and convenience items let players self-select what an experience is worth to them.

Virtual goods have software economics — no unit cost — so each sale of an item that already exists is almost pure margin.

Free worlds compound: more players make items and status more meaningful, which makes paid items more attractive.

Charge for desire, not access: when the product is free, the audience becomes the market and the margin lives in the things people choose to buy inside it.

Free-to-play swept the industry and became the default for mobile and live-service games worldwide; Nexon grew to 45-plus games in 190 countries, and Kim Jung-ju led the company until his death in February 2022 at 54. The model also drew a Korean regulatory reckoning over randomized items: a 2018 fine over false odds in Sudden Attack, a Supreme Court loss over MapleStory's manipulated probabilities, compensation worth 21.9 billion won to about 800,000 users, and a record 11.6 billion won fine in 2024. Selling desire, it turns out, comes with disclosure obligations.
