Ar Tonelico Submission

The game that sparked a multimedia franchise, Ar Tonelico is known for having lore that's so expansive and full of technical jargon it makes Kingdom Hearts look like FF1, one of the most unique soundtracks you've ever heard, and visual novel sections where you explore the character's subconsciousness to help with their inner turmoils and mental traumas.
PROS
Easy to follow combat involving charging up song magic to the thousands of percents
Amazing soundtrack consisting of rustic themes, futuristic themes, and otherworldly songs using a constructed language
Unique world built around a single tower that extends up to space

CONS
A few innuendos thrown around with the subtlety of a brick to the face
We turn off encounters halfway through the run, which does make the game significantly quicker but it does mean the later portions has lengthier sections of walking between bosses and story sequences
Cutscene heavy game
