First off, Fifth Element, thank you for your response.
There are some real differences as to how we view the game, which are peforce going to colour our viewpoints. So, as I said upthread, you may wish to take anything I say with a very large grain of salt.
That there is no simple answer. There is no one reason, and there is no reason that applies all of the time.
I only asked for one example. I am well aware that the circumstances of that one example will not apply to all times.
Because you cannot plan for everything. That's what you're missing. And if something you did not, indeed could not, plan for happens and it threatens to suck the fun out of the room, a DM should consider not having that thing happen.
You seem to be arguing that everything can be solved with a little planning. I would call that argument naive.
Herein, you may be right. Maybe I am naive. Certainly, you cannot plan for everything.
However, I would then ask, how do you explain that others, who also cannot plan for everything, do not have to fudge die rolls to compensate? I think that there is more involved than this.
Or you could choose to use a less loaded word. This is a fantasy game of make-believe we're talking about here. "The orc hits you, take 10 points damage" is dishonest, because there is no orc.
Every game ever invented is make-believe. Because there is no real knight, it is not any less dishonest if I "fudge" where I am allowed to move my piece.
"The orc hits you, take 10 points damage" is not dishonest, because it is understood by all particpants that both orc and damage are game constructs. There is no intent to deceive.
(This entire line of reasoning was deconstructed upthread, wasn't it?)
But dishonest is a terrible word to use there, because we're dealing with the imaginary.
If I said "I think you're right here", it would be a statement about something equally unreal (because it occurs only in my head), but it would also be untrue, and hence dishonest of me to say.
If the PCs encounter a room, and the DM says "You see an empty room", causing the players to enter, and then the DM says "The ogre in the middle of the room attacks you!" I really doubt that the players will accept "I wasn't being dishonest because the room, the ogre, and your dead characters are all imaginary!" as an excuse.
That's a pretty fine distinction. The rules say the characeter dies, but the DM can use his discretion to overrule it. That's a lie, of sorts, because it's contrary to the rule that the character should be dead.
Again, it is not a lie, assuming there is no intent to deceive. "I'm going to say Sir Robin is still alive, but loses his hand" is fine. It is above-board. Everyone knows that the rules are being bent....or even broken!
"Contrary to the rules" is not dishonest. Not telling the truth is dishonest.
Why not let the players give the a number of tokens, each of which must be "spent" to fudge the dice? As I said earlier, this would do two things: (1) puts the players in the driver's seat as to how much fudging goes on, and (2) maintains tension because the players can see that the token pool is decreasing. If the players feel like it, they can always add tokens back into the pool.
Eliminate the dishonest and it's all good, IMHO.
