"A bell curve distribution such as this is excellent for RPG gaming because though it does indeed introduce a degree of randomness into an event, the bell curve's statistical properties still favor character traits over absolute randomness." (FATE wiki)That statement is 100% false. Using FUDGE dice, or any dice rolling method, is no more or less random than any other (except weighted dice, I guess). The table they provide on the website clearly states that.
|4dF Modifier Result || Odds || Chance of rolling this result exactly || Chance of rolling this result or higher ||Chance of rolling this result or lower|
A "bell curve" property does not favour character traits over "absolute" randomness. e.g., your character has an engineering skill of 2. Lets say that to succeed at a task, she needs a result of 4. Using FUDGE dice, her chance is 18.5% (i.e., the chance of rolling two or more pluses.) Or use percentile dice, where less than 19% is a success. The randomness is essentially equivalent (give or take .5%) even though percentile dice are a uniform distribution rather than the normal distribution of FUDGE dice. Use one die, four dice, percentile dice, or a million dice, the randomness is the same. The chance of success is whatever the game designer, game master or players decide it is.
What FUDGE dice do, however, is give you a non-uniform distribution that you can use when you want to define varying possibly outcomes, each having varying probability. So, you could, for instance, define a series of results, such as:
- 4: Your sword cuts deep into your opponents neck. They slump to the ground and die, quickly, as blood seeps from the mortal wound;
- 3: The blade gashes armour and flesh from your opponent's left arm. They drop their weapon.
- 1 or 2: Your blade strikes hard against your foe's armour. They're shaken, morale faltering, yet steady themselves and grimace.
- 0, -1 or -2: Shield meets shield, bronze meets bronze. There is noise and sharp flashes of pain, but little else.
- -3: You trip and fumble, slicing into your left thigh. Walking will be painful and slow, at least for two weeks.
- -4: Not only do you fail to land a blow, your enemy ripostes and strikes your right hand. The weapon falls to the ground - you won't be able to use a weapon for two months.
You can do all this on percentile dice, of course, but FUDGE dice are much faster to assign. You can also apply modifiers with ease using FUDGE dice, which is quite impractical using percentile dice.
Every roleplayer needs a set of FUDGE dice. Don't leave home without them.
The FATE RPG makes great use of FUDGE dice.
