I say "new", because the copyright is 2011 on the comic and 2010 on the songs. It's less than 2 USD, DRM free, and really cute, so please show Mira some love!
A curious little JRPG gem that began life on the PC-88 and PC Engine CD (a version with exceedingly more fan service), Princess Minerva sees you in control of the titular royal lead along with her eight very distinct female bodyguards. Enter antagonist Dynastar and her own squad of eight all female (notice a pattern?) generals with the nefarious desire to turn every female in the kingdom into monster girls; with that you have the zany plot all setup and ready to go.
The core gameplay mechanics are interesting and the script is filled with humorous dialogue between Minerva and her crew. The series was popular enough to warrant both a OVA and manga series, and in the middle of the golden age of the 1990s it is easy to understand why: it could appeal to a broad group with the added bonus of actually being a good RPG underneath all the fan service. Veteran translation group Dinamyc-Designs released the complete English translation patch on Christmas Eve.
