In the interest of fairness and community brotherhood, I'd like to say that no one will judge your gameplay and look down upon you for it. However, in the pursuit of honesty I have to say that we will ridicule you and snicker behind your back. But what're you gonna do, right? Dwarves...
So, the idea is fairly straightforward. It's a sort of test or questionnaire, and each question adds or subtracts from a certain score, which can be translated into your Dwarvenly Factor. For instance, +2 points for every dead elven trader, -5 points for every civilian lost to ambush, +1 point for every civilian killed during a cave-in during megaproject construction. Math it all together, and get a number, which we will (as stated above) laugh at you for.
But what should the scoring card be? Certain things may seem obvious, but aren't. For instance, you might say +1 point for every steel bar produced. But then what? You've got an army clad in steel who can calmly destroy any invasion, and divert any Fun. Therefore I'd have to say -1 point for every piece of steel armor your soldiers are wearing, and +5 points for every leather armor being worn. This promotes a more brutal military and encourages Fun.
Which I suppose is the ultimate goal, not to measure the Dwarvenly Factor or the Win Power, but rather the Fun Coefficient. How prone is your fortress to Fun, and how unstable is it?
So some thoughts: Farm tiles are negative, active ghosts are positive, waterfalls are positive, killing invaders is positive, killing merchants is double positive, losing civilians is negative, losing military is either neutral or positive, room value of particular rooms are positive, number of missing limbs from living civilians is positive, number of cave crocs that swam up your sewers and into your dining hall is positive, number of captured cave crocs used to kill nobles is positive, number of tantrum spirals caused by cave croc noble killings is positive...
What should add, subtract, or otherwise perform math upon the scoring system?
