If you prefer your visual novels with more crime and less romance, then check out Crime Opera: The Butterfly Effect. Crime Opera bills itself as an episodic story focusing on the criminal Gallo family.
The trilogy was created over the span of three years. A demo is available for anyone who wants to get a taste for it. The demo fortunately runs on Windows, Mac and Linux.
Anyone pleased by what they see in the demo can help bring the visual novel to fruition. It’s currently on Kickstarter. The campaign ends on December 24.
