VNs are like a theater play that you direct. You sit and read, while making "life-changing" choices. Most VNs are made by small studios so they wont contain any action except some "horizontal recreation" ( ͡° ͜ʖ ͡°). A good visual novel will deeply engross you in its story and make you want to know more and MORE until you reach 100% completion by choosing every possible outcome.
or...
Its made by some autism company bloated with hentai and shit. With a shitty story and only exists to take ure money.
I trust you will make the right choice if you ever decide to pick up a Visual Novel
