What sorts of guiding moral principles govern how you run your games?
I'm very hard on players showing up for the game. If you say you want to play: then show up on time. Sure, something might come up...but you can call/text. And I'm not forgiving if you will always have "some problem" every week: why keep saying you "want" to game if you never show up?
Know the game and game rules. Have a character and other items.
Let the Dice Roll where they May--whatever is rolled, happens. I like randomness, more then anything else.
No Recons- If it happens, it happens. I will never as a DM recon anything, but in the game context it's possible an 'force' or 'NPC' might undo something, though nearly always with a cost. But no altering of reality.
Status Que type game--I'd more commonly say my game is not fair and not balanced. The world exists as it is, nothing is ever 'set' to the PCs level.
Consequences are always enforced- character actions, will cause things to be set in motion
There is no requirement for the characters to "do something" or "take an action" to trigger anything in the game world. And things in the game world might come after the characters for any story or plot reason.
I run a hard game. It's made to be hard, don't expect anything to just be easy or effortless. You will likely find things "too hard" or "impossible", but you should not fall into that hole. Anything can be done, if your willing to try and put in some effort.
