Never read any...
But more like I've never had the chance, nor clue on how or where to begin with. I've always been considered a low-tech kind of person, so I feel overwhelmed if I end up with a PC of any kind due to lack of experience and sources to help me on dealing with them. And then there would be the issue of what VN to even begin with. Unlike video games, I don't know what kind of genre would suit me in the world of Visual Novels.
...But seeing that my "first" anime is Air, and after knowing it originated from a VN, then I guess that I could start with that one. I'll have plenty of time to regret or praise it afterwards.
But for now, I guess I'll keep a tab on what priority goes before VNs, since I don't have the privacy to experience them unless there's one on a portable console.
