There is a sliding scale along which most adventures are delivered in terms of the experience it offers to the players. I would suggest something like - open world - West Marches - campaign - module - episodic - one shot. I wouldn't try and establish this as a new Beaufort scale for roleplaying games but I have been in many situations when games have broken down as roleplaying styles conflict over these issues and quite often the players dont even realise it. Yes there are inevitable character clashes between the narrative players and the rules junkies but being mindful of the gaming style will mitigate issues down the line. Whilst a GM should open up a dialogue with the players before a game even starts in order to make the context clear players should ideally have experience off all of these environments and adjust their style accordingly.
