While Concerto Gate is actually signed for Taiwan, Macau and Hong Kong, the publisher is actually located in Hong Kong. Once a much-anticipated title in the English market which never saw the light, this turn-based classic will be getting the latest updates from the still-running Japan server.
Officially known as “Concerto Gate 2 Version 2.o: Rosenberg Academy and Seven Worlds”, the game will officially begin beta testing later this year. If you are interested, the website can be found here. Do note that the wordings for Taiwan/ Hong Kong is Traditional Chinese.
