From the introduction:
3d6 Fudge is an alternate way to play Fudge, especially when you don't have Fudge Dice available. It was inspired by the Min-Mid-Max damage section in Fudge. It does change how Fudge feels a little, so this may or may not be anything you're interested in. In particular:
- adjectives are awkward to use in 3d6 Fudge - it's best to switch to numbers;
- the numbers associated with Adjective levels have changed, which long-time Fudge players may find confusing;
- there are no "target" difficulty levels - instead, a roll is compared to the character's level;
- although it requires only elementary-school level math, it's still one step further into "calculations" than Fudge Dice, allowing the possibility of being drawn away from playing the role.
There are no other real changes. You still can use all your regular Fudge habits and customizations.
