Cosmic Fantasy 3: Bouken Shounen Rei — About this game
Rei leads the third Cosmic Fantasy adventure through a mixture of planetary exploration, encounters with companions and turn-based battles. Animated story scenes connect the role-playing sections, keeping the cast and its changing relationships at the centre of the journey. Explore each safe location before advancing, use conversations to identify the next destination and prepare the party for the enemies waiting outside. New companions change what the group can do, making it useful to inspect abilities rather than repeat the same command for everyone. The series' combination of space adventure and character drama gives the quest its distinctive tone.
