According to Tørnquist, "The Longest Journey" experienced "solid sales across Europe" before its release in the United States. The game sold 15,000 units in Norway by May 2000, while overall European sales totaled 100,000 units by September 2000. It launched in Germany with a shipment of 40,000 units to retailers; Chris Kellner of DTP Entertainment, which handled the game's German localization, reported its lifetime sales between 10,000 and 50,000 copies in that market. In Spain, the game sold 50,000 copies after roughly one year, a commercial hit for the country. Its English release was purposely delayed to prevent imports from cannibalizing local sales across Europe.
