Scarlet Curiosity is a good, if short, RPG-Brawler that makes decent use of the setting that ZUN has created for the Touhou series. However, repeated enemies, generic looking stages, and the inability to block attacks from the beginning are a bit grating and prevent the game from reaching its full potential.
Touhou Genso Rondo Bullet Ballet is a game that successfully takes Touhou's gameplay and turns it into a two player game that is fun to play and has depth to boot. However, its lack of variety and features put a minor damper on an otherwise good experience.
Sophie is a fun game that is ultimately marred by a tedious advancement system, vague mission objectives, and the choice to downplay its battle system in favor of character interactions and dialogue. If it were to balance these elements better, Sophie would easily have been a much better game worthy, but as things stand we can only hope that the next game in the trilogy will bring more balance to Gust's trademark series.
