French developer and publisher Ankama Games revealed that its free-to-play and Flash-based massively multiplayer online game Dofus
has attracted more than 30 million registered players since its launch in September 2004.
Of those registered players, 3.5 million pay a monthly fee of around €5 ($6.74) for full access to the game's content, the company disclosed at its Ankama Convention in Paris last weekend, according to a report
from consumer site Eurogamer. Based on those figures, the French studio brings in some $23.6 million each month from just subscriptions.
The turn-based online strategy game draws an average of one million players each day, peaking at about 250,000 concurrent users. French gamers make up 60 percent of Dofus's audience, and the MMO also has a significant amount of players in French-speaking countries like Belgium, Switzerland and Canada, as well as in Spain and Latin America.
Ankama has made several efforts to strengthen and expand the Dofus
franchise, including a 2.0 update and code overhaul last December, a player-versus-player spin-off titled Dofus Arena
(currently in Beta, launching on June 21st), and a manga that has so far sold around 800,000 copies.
