Haven't played AI: Somnium Files yet, but for the others, definitely. As a general rule of thumb, I'd say: If people who are averse to reading wouldn't play it, it's a visual novel 😄 I am kinda aware that there has been past discourse on AA's and Dangan's classification due to the presence of gameplay like mini-games and point & click stuff etc. But 90% of the time, you are still reading stuff, it's the main thing you do.
