The biggest online games are graying. League of Legends lost 55 million monthly players; Fortnite's US-teen reach fell to 37 percent. The original fans are aging out, and new ones cost 30 percent more to win.
The biggest online games are quietly graying. League of Legends has fallen from 180 million monthly players in 2022 to about 125 million in 2025. Fortnite's reach among US teens has slid from 53 percent in 2019 to 37 percent. World of Warcraft's largest age group is now 25 to 34 — the same people who started in 2004, never replaced by younger players. Meanwhile the cost to win one new player has jumped 30 percent in a year, and more than 90 percent of 2025's new live games already lost their crowds.
The market underprices this because flagship titles are valued as if their fans stay loyal forever. They do not: aging is slow and steady, so the revenue leak is easy to ignore until it compounds.
Electronic Arts is most exposed, with 74 percent of its 2024 revenue from live games. Tencent owns League of Legends. Take-Two runs Grand Theft Auto Online. Roblox depends on holding younger players. Microsoft owns World of Warcraft. Each leans on long-running titles whose original audiences are growing older.
Why this matters. Long-running online games depend on players who stay for years and keep spending — but the original fans are aging out and fresh players cost more to win. Game makers who lean heavily on one or two big titles get hurt first, because a slow leak in players becomes a slow leak in money. Lenders, operators and investors should care because these titles are valued as if loyalty lasts forever, and it does not.

TheGamer / 2025 launch analysis
Attention is climbing. the market is starting to price this in — the early window is closing.
Our middle estimate puts $3.2 billion of yearly flagship online-game revenue at risk (range $2.2 billion to $4.7 billion, about 6.5 percent of the $50 billion entrenched-flagship pool), as League of Legends monthly players fall from 180 million to about 125 million, Fortnite's US-teen reach drops from 53 percent to 37 percent, and World of Warcraft's biggest age group ages to 25–34 with no new generation arriving. We judge this a lasting shift at 59 percent likelihood, with a Blindside score of 78 out of 100 — underpriced because flagship valuations assume loyalty never fades, while independent analysts confirm decade-old titles shed 5 to 10 percent of their peak players every year.
