I can't help but be patronizing when dealing with ignorance, can I?
VNs with choices are like huge story puzzles (well good ones anyway), where you have to reason you way through choices to desired outcome, it feels like playing a game, because it is.
People don't need guides for books or for movies, but many need those for VNs with choices, because it's choices based gameplay. Choices is gameplay in this case.
or we can agree to disagree, but as we are on discussion boards, discussing all sorts of stuff is kinda expected.
