This week's Famitsu issue featured the first Sigma Harmonics review. Forever Fantasy has translated what the four reviewers had to say about the game:
Average playtime to first game completion: 20-30 hours
Including all bonus/optional content: 50+ hours
Babadaichi (Final Score: 8)
The visuals are beautiful and appealing, but underneath is a game structure that requires serious thought to solve the detective elements, the results of which affect the battle portion, and so on. Moving around and the normal battles can get a little tedious, but there are enough mechanics and features to keep gamers engaged.
