In just four days developer Bigpoint managed to make $2.6 million selling one virtual spaceship in the sci-fi browser-based MMO DarkOrbit.

According to a report from GamesBrief, Bigpoint CEO Heiko Hubertz revealed that over that period 2,000 of “The 10th Drone” — a rare and helpful in-game item — were sold. The catch is that the item costs €1000 (US$1,335) each, which means that sales of that single item reached into the millions in less than a week.

Launched in 2006, DarkOrbit currently has 65 million registered users.

In 2010 Bigpoint earned approximately €200 million from virtual goods sales.
