In a brief report on Tecmo Koei's buyout of Gust, Nikkei writes that the publisher plans on turning Gust's Atelier series into a social game.
Atelier has most recently appeared on the PlayStation 3 through the Arland subseries, which includes games like Atelier Meruru, Atelier Totori and Atelier Rorona. The games combine adventure, RPG and item synthesis elements.
For fans worried that the Atelier series as we know it may be coming to an end, it should be noted that Nikkei's report did not say that the series will be exclusively social from here on out. It's possible (and likely given recent sales) that Tecmo Koei is planning social developments in addition to standard games.
