I'm sure most of us have read about "GNS" (Gamist/Naritivist/Simulationist), "The Big Model" and other theories of role playing. I have even tried writing a few theories of my own. However, the question remains, do we use it?
While I certainly agree with the notion "system does matter" behind these aspects, I don't find myself sitting down to write with an agenda. Instead, its a case of writing what seems to work based on prior games I've played. The first role playing game I ever attempted to design was basically just all the house rules I'd written for Rifts in one collection.
Now perhaps its a matter of I'm so deeply embedded in a cretin style of gaming that I don't see the forest for the trees. I prefer things with a bit more crunch and rules as the arbitrator of disputes over free form & GM fiat for example. But, no two of my games are exactly alike system wise, so I don't think the agendas are merely subconscious...
Anyway - how do you use these theories? And if you don't, how collaborate towards a thought system that does prove more useful?
