I was revisiting the result distribution of the FUDGE / FATE dice for the 4d6 option, when I thought about applying a variant of the classic Hero System BODY roll to reading the dice. In this option:
1 = -
2 through 5 = 0
6 = +
This results in this distribution (courtesy of www.anydice.com):
In essence, the chances of a +4 or a -4 are 0.16% combined. This means that the modification to someone's basic ability rating is more or less likely to take place between the -3 to +3 range. There's a chance that there might not be enough variance in the rolls during gameplay, but we'll see. Certainly not as varied as the range for the standard FATE roll below:
It makes me think that perhaps the standard FATE roll is better, but I want to tweak it because -- in the absence of actual FATE dice here in the Philippines, it may be easier to just explain that 1 is -1 and 6 is +1 and all the other dice faces are 0.
