Baroque was popular enough to spawn a manga named Baroquism Syndrome, which ran in Sega Saturn magazine. The storyline detailed all of the events that led up to the great heat wave destroying the world. Apparently Sting liked this idea and commissioned a game based off this story. And thus Baroque Syndrome was produced, which plays nothing like the original game and is actually more of a visual novel.
A prequel to the post-apocalyptic RPG Baroque, Baroque Syndrome chronicles the events that precede the supernatural apocalypse of the original game, in which all of earth has been devastated by a massive heat wave.
You take the role of Kitsune Kanazawa, a Japanese student that becomes entangled in the investigation of a series of supernatural murders, which will slowly introduce key characters who will play a part in the upcoming apocalypse.
The game is played as an interactive novel, with 2D still pictures of settings and characters being the main graphic elements, and all actions being described via scrolling texts. At several intervals you will have to make a choice that branches the plot in different directions, but that's all the interaction you get to make. (Source: PsxDataCenter)
