Yes, it is. The fact that it's based on a true story gives it an extra layer of authenticity. The characters seem more real and the events are often more impactful because they actually happened.
First, you need to have a good story idea. This is the foundation of a visual novel. Then, create the characters, design their appearances and personalities. Next, you can start writing the script, including dialogues and plot development. For the visual part, you can draw the backgrounds and character sprites yourself if you have the skills, or you can hire an artist. Also, choose a suitable game engine like Ren'Py which is popular for visual novels. Finally, add music and sound effects to enhance the atmosphere.
Well, making a graphic novel involves several steps. Start with brainstorming for a concept. Once you have it, write a script. This is like the blueprint for your graphic novel. When it comes to the art, you can start with thumbnails of each page to get the overall composition. After that, draw the full - sized panels. Consider the perspective, proportion, and expression of your characters. For the text, make sure it's legible and in harmony with the art. Also, think about the pacing of your story. How fast or slow do you want the reader to move through the pages? This will affect how you space out your panels and text.

In my opinion, it's hard to say. The anime can be more accessible and exciting, while the manga gives a purer form of the creator's vision. You might want to try both and decide for yourself.
