I find myself more of a storyteller, with cinematic influences. Rules are important and need to be worked with. They keep the game fair and balanced, as well as giving the troupe a common langauge/ frame of reference to resolve issues. However, to move the game beyond a human moderated videogame, you need to tell a story of some type and length. This engages the players emotionally, as well as intellectually. Description and maintance of the "beat" of the game are more important to a successful and memorable session than simple tactical/ numeric results.
I personally find G/N/S as bankrupt theory. It fails to include all modes of gaming (those that don't conviently fit are quickly swept into one of the above, with a spin to minimize their impact). An RPG/ campaign/ or gamer has to be a combination of many things, and can not be pigeonholed so easily.
