Rhapsody: A Musical Adventure (1998)

Rhapsody: A Musical Adventure, released in Japan as The Puppet Princess of Marl Kingdom (マール王国の人形姫, Māru-ōkoku no Ningyō-hime) is a tactical role-playing game for the PlayStation from Atlus USA and Nippon Ichi Software, the creators of Disgaea, and is part of the Marl Kingdom series.
It was released four times in Japan — once in 1998, then again as The Adventure of Puppet Princess + 1 in 1999, and then again as The Adventure of Puppet Princess (PSone Books) in 2001, and then a fourth time for the Nintendo DS on August 7, 2008. The game was released in the United States, in 2000 and in 2008 and is the only game in the main series to be released outside Japan. A version of the game was also released on mobile phones.
Rhapsody, along with its sequels, are considered musical RPGs, meaning in place of FMV cutscenes, there are musical numbers, complete with vocals. The game is also known for its "overwhelming cuteness" and low level of difficulty. Although this may make the game seem geared towards a younger audience, in Japan, the game and series in general has seen much success.
