Hangame, one of the bigger MMO publisher in Korea, seems to be the company with the saddest G★2009 lineup. So far on their G★2009 special site, only 3 games are listed, being TERA, Warhammer Online and HANJAMARU, a casual social game teaching players Chinese. Even with the weak lineup, Hangame is going to sponsor 8 reporters for G★2009 (accommodation and air tickets), provided they do exclusives reports about thier games.
However, do note that Hangame has several other new MMOs in production or in Closed Beta, so some surprises might be in store for the convention.
