I also tend to say when I run a certain genre how things will generally work. Like with Star Wars RPG, I err in favour of the players because the setting is heroic and players should do heroic things and reap the rewards.
Babylon5 I tend to run straight as the book suggests and my players have learned to get sneaky and cagey like the heros in the game.
L5R I tend to run brutal and quick when the blades come out, and the system backs me up in quick character deaths. But I always reward character deaths in style and fitting the setting. makes for better drama
Cyberpunk....well. I have no scruples and no mercy if the players are being stupid. They deserve what they get 
Again, it depends on the setting. I don't work to 'get' my players. The tend to get themselves in enough trouble as it is so I needn't go after anyone.
A brave little theory, and actually quite coherent for a system of five or seven dimensions -- if only we lived in one.
