In movies like, "The Good, The Bad, and The Ugly", "The Wild Bunch", Once Upon a Time in the West", "Django", 3:10 to Yuma, There is no "Good Guy with a White Hat on".
As a matter of fact, a "Good guy" doesn't exist.
That was something that some tool in hollywierd came up with to sell movies.
The real west was hard core, violent, and cutting edge.
The "rule of law" was Winchester, Colt, and Springfield.
"He who has the gold, Soulstone, or minions to push thier agenda, makes the rules."
Your best bet to as close to a "Good guy" you are probibly going to find in this game might be one of those hired guns, Mercenaries, or some of those "Human" type gunslingers.
We're supposed to be playing in a world of "Wild wierd west, Gothic cobblestone streets of jack the ripper, or some sort of sewer-world where everything is like a psyched out conspiracy.
I play another game where the "Religious" thing is an element, and unless you are playing in a certian type of group with that sort of a sensability of depravity, you arn't going to get a large following for this sort of thing.
As for your faction description, you have those elements in the already established factions.
No one is good or evil..er, then the other. The factions have about as much of an equal footing then any I've seen in a game, and I think that might be what I think is the cool part about it.
Other miniatures games out there all have some sort of whooooo whizz bang!! that is the be all and end all that you have to have to "Win the game!".
That special H bomb model, or character that pretty much ends the game when he or she pops up on the table.
In this game, I might be new, because I don't see it yet.
The best thing I think is that each and every faction has something that they bring to the table, and you can play them goodie two shoes, or cold bloodedly ruthless.
Cowpunk. at it's best.
