Monetising Pedigree: Genealogical Gacha and Racing Heritage in Uma Musume: Pretty Derby

Chelsea Russell's paper examines Uma Musume: Pretty Derby, a Japanese mobile gacha game by Cygames, to argue that some free-to-play systems monetise lineage as well as characters.

• The paper argues that some free-to-play games monetise lineage as well as characters, coining the term "genealogical gacha" for systems built on real-world thoroughbred pedigrees, probabilistic trait inheritance across generations, and paid access to better ancestors and training supports.
• Its central claim is that horse racing's speculative logic moves from state-regulated wagering into platform microtransactions, where variance is preserved but relocated into repeated pulls and long-horizon saving.
• The case study is Uma Musume: Pretty Derby, a Japanese mobile gacha game by Cygames, analysed through an interface walkthrough, official update communications, multisited netnography of Japanese- and English-language player spaces, and a small set of semi-structured player interviews.
