magic triangle

Lyrical Nanoha: magical girl spin-off of the Triangle Heart eroge VN series Prisma Illya: magical girl spin-off of Fate/stay night + Fate/hollow ataraxia eroge VNs Madoka Magica: Not a direct spin-off but creators wrote/directed several VNs

There's plenty of similarities in the marketing strategies, themes and motifs, and some more direct shared production history (Shinbo working on both Nanoha and Madoka, Urobuchi writing a Fate prequel, etc), but I'm intrigued by the... otaku crucuble of the VN scene suggested here, I guess. no thesis just putting strings on a corkboard and going "someone should check this out huh"
