I've never understood people wanting to record their own voices while doing these VNs.
I first learned about VNs seeing some recordings on PH of the game play. There was one I was following, where the dude posting it decided he wanted to start recording his sessions with him voicing the text and him on camera down in the corner - I could turn off sound so it wasn't AS bad. Then a couple of others decided to take it a step further by removing the text and making you rely on their voices (one was in French) to follow the dialogue - one removed the text by going into the video and censoring the text box, while the other blew up the video so most of the text was outside of the window. Some of the most annoying, narcissistic bullshit I'd ever seen in that kind of setting.
