Angelique Duet

Angelique Duet can be best described as romance simulation. It is a spin-off of the first Angelique game published 12 years earlier and one of the titles made to celebrate Koei's twentieth year anniversary. According to Ruby Party commentary, this title answered popular fan demand for an option to play as the first protagonist's rival, Rosalia.

The Nintendo DS version includes a Communication Mode to take advantage of the console's wireless connections. Players can send letters to their friends through an in-game messaging system and visit each other's rooms to trade items. Animated movies are condensed into a collage of key frames and subtitles.
