C. The Case Against D&D.
1. The "You're Learning It Wrong" Objection.
The problem with this as an objection is that it isn't D&D-specific. It is true for whatever game is your first. If your first game is D&D, switching to other styles is going to be difficult. If your first game is FitD, that's going to be your formative experience, and anything else with a different process or goals of play will be weird to you.
