This is a great point, and I definitely agree, and I haven't thought about it in this way. I don't think that I've ever ran into a group where our expectations would be so much different that it would cause an issue, but it's a great thing to keep in mind. Now that I read it again, I think I should add that I don't think that it's wrong to play RPGs as a board game, and I don't really mind if someone does even in our group and I'm having fun either way, but I mostly felt like it's a little bit shame that it may not even occur to some people that you don't have to focus mostly on rules - since thats what most of the game book is about, and can do it differently, especially when you're starting out. Which is also a good thing to keep in mind, to discuss and make the options and expectations clear before starting.
