I’ve been thinking about Chain Smoker being a profession, it seems much more like a negative trait you can have rather than a profession. The professions seem to be more like things to help you start out in a game, and then there is a chain smoker thing which does reward you with points, would make more sense as a negative trait similar to asthma.
Professions can help or hinder. Chain smoker is one of the latter.
Chain smoker comes with cigarettes, so it does in fact determine starting equipment.
You also start with dress shirt/shoes instead of t-shirt/sneakers.
