Valve allows users to cash in on the virtual items they have won in two ways. Users can sell the items they won through Valve’s own virtual marketplace, the Steam Community Market, where they can use the proceeds to buy other video games, video game hardware, and other virtual items. Users can also connect their Valve accounts to third-party marketplaces where the virtual items can be sold directly for cash. The OAG’s investigation found that Valve facilitates and even assists these third-party marketplaces in their operations.

All three games feature an optional mechanic where players can pay real money in exchange for “loot boxes”: a virtual item that drops a randomly-generated piece of cosmetic gear that can be used in-game. Most of these items have no mechanical impact and are there strictly for looks, such as silly hats in TF2 or neon-painted “weapon skins” in CS2.

Despite their lack of actual effect, loot boxes and item trading are both an extraordinarily lucrative market for Valve. Virtual items for these three games have been sold for staggering amounts of real money. One estimate cited by the AG’s office indicates that the market for Counter-Strike skins alone was worth over $4.3 billion as of last year.

While Valve absolutely benefits from the strangely frenetic market for virtual items in CS2, TF2, and Dota 2 — it sells these loot boxes in the first place, and hosts the secondary market for them via the in-app Steam Marketplace — the occasionally shocking prices for these items is part of a player-created economy. The lawsuit may be partially aimed in the wrong direction.
