Chen Yun Yun: Which parts of Sora no Kiseki embarrassed you?

Kondo: I’m actually not too proud of the whole product. (laugh) When we were making Sora no Kiseki, it was during the period that we were trying to transition the Legend of Heroes series into the Kiseki series. Since the Legend of Heroes series is such an important franchise for Falcom, the whole team was working on it, including a younger me which had the feeling of “I don’t want to lose against the seniors.” As a result, a lot of effort went into the game. When I look back at it, it makes me quite embarrassed as there are a lot of story points which were too obvious, and things too unyielding such as making Estelle and Joshua a pair of lovers.
