# FATE dice rolling methods

I own a couple of games based on the FATE system (which is, in turn, based on the FUDGE system), and there are a couple of different approaches for rolling dice that appear in them.

The classic system is 4dF. A dF is a FUDGE die and has six faces representing the numbers -1, 0 and 1 twice over. It is a d3-2.

Starblazer Adventures uses a different approach and rolls d6-d6. This has the advantage that you don’t need to run out and buy dice that are so specialised that your friendly neighourhood gaming store doesn’t sell them.

This morning I decided to invest a few minutes into doing some analysis and comparison of the two systems (no doubt duplicating other people’s work, but entertaining myself in the process).

I generated all possible results that each of the two systems could provide, and converted them into percentages and then charted them.

Total 4dF 4dF % d6 – d6 d6 – d6 %
-5 0 0 1 2.78
-4 1 1.23 2 5.56
-3 4 4.94 3 8.33
-2 10 12.35 4 11.11
-1 16 19.75 5 13.89
0 19 23.46 6 16.67
1 16 19.75 5 13.89
2 10 12.35 4 11.11
3 4 4.94 3 8.33
4 1 1.23 2 5.56
5 0 0 1 2.78

There isn’t much to choose between the results, although the FUDGE dice give slightly less variance and are more likely to hit closer to zero.

Interesting…
What do you think the implications are?
My take is that for Starblazers you have a little bit more chance to do something extraordinary (and at the same time something awful).
Both have the same mean, but the standard deviation seems to the important parameter here…
