"Ultima Online"s sales rate was the fastest ever for an Internet-only game by 1997, and it led Electronic Arts to declare the title its fastest-selling computer game of all time. A writer for "PC Gamer US" considered this speed the possible cause for "the many reports of lost orders, delayed pre-orders and stores out of stock that occurred when the game launched." In mid-November, Electronic Arts revealed plans to ship an additional 80,000 units of "Ultima Online" worldwide, including 15,000 for Japan. The majority of its first shipment had been targeted at the United States. On November 20, the game became Japan's best-selling computer title of its launch month. "Ultima Online" reached 70,000 global subscribers by early December, of which Japan made up 8,000 and Europe 5,000. More than half of the title's sales by that time had occurred outside the United States, despite the fees for long-distance calls between international modems and the game's entirely North American servers of the period. The game had fallen from PC Data's monthly top 20 for the United States during November, but the firm tracked 87,000 sales of "Ultima Online" in that country alone through the end of 1997.
