This is not interesting for me. I want more ambiguity in the game than this.
"Do as thou wilt shall be the whole of the law" seems less than ambiguous to me - although your later post clarifies this greatly. It is an excellent post - xp if I can
I think N'raac's example of the two LG characters gives a good chance to show how the two play styles work and I think, showcases some of the strengths and weaknesses of the different approaches. Now, before I go any further, I want to posit a baseline. No one is being dishonest. Everyone honestly believes what they are saying and no one is being a dick. There are no bad players or DM's in the example groups. There, with that boilerplate out of the way, let's look at how things play out at the two different tables.
Scenario 1 -Mechanical Alignment Table- two players are playing LG classes where alignment has specific impacts on the class (probably cleric or paladin, but there are others) are faced with a difficult situation. One LG character decides that he wants to torture a prisoner in order to gain information necessary to succeed at their goals. The other LG character opposes this, as he sees torture as evil.
Player 1: I'm going to torture this prisoner to get the information we need. If we fail, many people will die and LG posits that the greatest good for the greatest numbers is a primary consideration. Yes, torture is not something we'd do every day, but, there are extenuating circumstances and sacrificing this one guy means that we save many more.
Player 2: The ends do not justify the means. That's a very slippery slope and many horrible things have been done in the name of the "greater good". Torture is evil. Full stop. Don't do this.
Both players turn to the DM for a ruling. Is this an evil act or not. Since there are no "aha gotcha" rules in play, the DM makes an adjudication and the players play accordingly.
The strength here, to me, is consistency. Everyone knows where they stand and can act accordingly. Regardless of how the DM rules, everyone knows which way is up. It's faster certainly and resolves a lot of inter-party conflict. The weakness, though, is, at the end of the day, the DM here is telling one of the players that he's wrong. Depending on who the DM backs, the other player now has to adjust his character to fit with the ruling. if the DM says that torture is evil, no matter what, then Player 1 either has to conform to that ruling or risk mechanical punishments for not doing so. Again, presuming that both characters are playing classes where alignment matters.
To me, part of this strength is a consistent tone for the game. Are we playing larger than life adherents to Good, or are we playing battle-hardened, jaded mercenaries? Players should be coming to the table with characters that fit the game's tone, just as I would not be building The Punisher to play in a four colour superheroes game (since Bats and Supes keep showing up as D&D Paladins).
Scenario 2 - Descriptive alignment table - Two players are playing LG classes, but, because alignment is descriptive, there are no mechanical penalties for straying outside of alignment. One LG character decides that he wants to torture a prisoner in order to gain information necessary to succeed at their goals. The other LG character opposes this, as he sees torture as evil.
Player 1: I'm going to torture this prisoner to get the information we need. If we fail, many people will die and LG posits that the greatest good for the greatest numbers is a primary consideration. Yes, torture is not something we'd do every day, but, there are extenuating circumstances and sacrificing this one guy means that we save many more.
Player 2: The ends do not justify the means. That's a very slippery slope and many horrible things have been done in the name of the "greater good". Torture is evil. Full stop. Don't do this.
The discussion continues for some time. The DM does not intervene. Eventually Player 1 puts it to the challenge - either Player 2 can forcefully stop him, or he's going to go ahead and torture this guy. Player 2 has his character leave in disgust to wait outside.
Why could the same result not occur under vision 1? The GM rules, and Player 1 says "Then the Tenets of Good are wrong. My character will do what is right - save those lives - either Player 2 can forcefully stop him, or he's going to go ahead and torture this guy." If anything, I have more respect for PC 1 in this situation - he knows that this will carry a personal cost, but he will nonetheless be true to his beliefs in what is right, though even the heavens themselves rally against him.
The strength here is that the DM is in no way telling the players how to play their characters. And, it allows for alignment conflicts where the players themselves have to find some sort of resolution. It's interesting to me, here, that you can make a pretty decent case in either direction. The alignment descriptions are broad enough that it's possible for either character to be right. As a DM, I'd be sure to test this at a later time as well. If Player 1 believes the ends justify the means, then, how far will he go with that? Is it always true? What's the limit? And, additionally, I would want to add in more conflict between the two characters in new situations. How will they handle things the next time around? Will there be any give or take between the two viewpoints? Can one viewpoint win the other over?
First, these are moral and ethical conflicts, but we have tossed out alignment, so it is not an alignment conflict. Anyone and everyone can call himself LG, no matter what actions they take in the alleged name of those principals. That's not a positive or a negative.
Second, what actually happens at the game table? PC 1 abandons his principals and walks away? How happy is PC 1? Now, if my PC feels strongly about this issue, he's likely to:
- walk from the PC group entirely - I brought a principled warrior of Good and Righteousness, a Hero, to a game of ruthless thugs - sorry, I misread the tone of the game, so I will make a ruthless bastard character to better fit the murderhobo game we are actually playing.
- push the matter to confrontation - will the rest of the party permit or oppose this atrocity? Either PC 2 goes, or PC 1 does - they are simply not compatible.
- take PC 2 up on his challenge - if you want to torture those helpless prisoners, it will be over my dead body. We have established that Paladins are OK killing for their principals. Having "PC" tattooed on his forehead does not mean I will treat his transgressions differently than anyone else's.
The downside here is it could very well blow up in my face.
The above certainly reflects examples of this.
The game grinds to a screeching halt as the two players get locked into a never ending debate and endless alignment wank. And, true, it also means that there will be times when there is apparent contradiction - two people sharing a morality, possibly worshipping the same god, can hold very contradictory viewpoints. Again, I can see how this could be problematic for some people.
PC vs PC is also problematic for some people. And I note all of the same results can occur under Model 1 as well. It only requires PC 2 sticking to his viewpoints, whether or not they are the views of his religion, or his (previous?) alignment. In fact, both characters could easily be, and remain, LG in the scenario set. Even if I accept PC 2's act, however motivated, remains an evil act, a single evil act does not cause him to change alignment. If I accept his desire to protect the innocent balances out his willingness to torture these prisoners, then we move to a N act, and he doesn't even lose Paladinhood. Yet the PC's can still have very different opinions, refuse to work together or even come to physical violence over the appropriate approach to this situation.
The fact that the GM expresses his opinion, and/or the opinion of the Force of Good, does not change the free will of the characters or their players. I note nothing stops a GM from saying "By my own morality, I agree that the right thing to do is torture the prisoners. But that is not what the Forces of Good believe." Further, nothing stops Player 1 from saying "By my own morality, I agree that the right thing to do is torture the prisoners. But that is not what my PC believes." Nor does anything preclude Player 2 from saying "By my own morality, I agree that it is wrong to torture the prisoners. But that is not what my character believes." And every person can say so with perfect honesty.
