thanks for your explanation but the section in literature etc is in no way intended as a list of everything which mentions chopin otherwise it would be endless it is there to give an idea of some of the most significant presentations of chopin which shed some light on his historical life and works the video game sheds light on neither of these it's just apparently a fantasy world in which one of the characters is named chopin and which uses some of chopin's music as arranged by others unless you have a reputable source which says different
