Japanese social gaming company DeNA said a game for its Mobage social game network has topped the Google Play top-grossing apps chart in the US.

Smartphone social card battle game Rage of Bahamut, made by Japanese developer Cygames, is also ranked second in Sweden, sixth in Canada and seventh in the Netherlands.

“Rage of Bahamut demonstrates that Japanese developers’ expertise in social games can be applied effectively overseas,” said representative director and president of DeNA, Isao Moriyasu.

Rage of Bahamut is a fantasy adventure game requiring players to use powers found within cards they find as they roam the fictional world. Players can choose whether to represent man, gods or demons and pursue battles and quests to advance.

Neil Young, CEO of DeNA’s US business ngmoco, said his team is looking carefully at successful titles available on Mobage to see how their success can be translated globally.  “The instant success of Rage of Bahamut is an encouraging indication that people everywhere simply love to play great games,” he said.

Moriyasu added that the success of the game shows that browser-based games can generate “a remarkable average revenue per user” in the West, when coupled with the right design and approach in making them available to users.
