Pathfinder's Lawful Good beliefs don't seem to coincide with mine.
Naturaly ...
I mean feel free to corect me, but as far as i know ... if you are "Lawful" it means only that there is *some* set of rules that is not your own, that you are following without questioning and often even hesitation.
For example ...
Devils are Lawfull ... Githynaki are Lawfull ... there are several Lawfull Gods ...
And yet no two set of Laws from theese cases are same ... its just existence of some order, that means they are Lawfull, no matter what kind of order it is ...
Someone mentioned earlier that in some other game, one Lawfull option was to persuate a monk to betray his order ... i dont think that is bad example, as long as character who does that have in those Laws somewhere stated that everyone who dont follow their believe, should be converted.
IF so ... then such action is perfectly lawfull imho.
As far as what effect to gameplay, it boils down to spells and items mostly - at least from a pure mechanics perspective.
I see ...
Well this would seriously affect my decision.
I mean if the game would have option to strip my Cleric or Paladin of all their powers, bcs i didnt pick the *right* option in chat ... that would suck ... and i would rather have none.
Same goes for conversations ... if i would be restricted to say only things that goes perfectly with my aligment ... that would suck aswell.
On the other hand tho ...
If the game would use aligments as some sort of guidances, that would only help me understand the world better ... like having certain dialogue choices red, to show that they are direct oposite of what would character with such aligment say (as angry DM would probably mention if i would try to do that) ...
Well ... i would like that.
But then again on the third hand ...
If the game wouldnt recognize your aligment at all in any way ... there is no reason to implement it at all. :-/
