A light engine TTRPG with a solid structure, using only d³s.

Thrice Fantasy is a flexible and comprehensive TTRPG, with a fresh and flowing
gameplay. The rulebook allows you to play in fantasy settings. Thrice Fantasy
is the first product to use the Thrice engine, a rule system that will be
employed in various styles and genres, as we'll explore in upcoming
Thrice-based releases.

I won't post the whole kickstarter detail, but I thought the custom dice was
interesting.

This breaks down to:

need a 1: 16.6% (1 in 6 chance)
need a 2: 33.3% (1 in 3 chance)
need a 3: 50% (1 in 2 chance)

Using a d6 as suggested would be:

need a 1: (roll a 1) : 16.6%
need a 2: (roll a 1, 2) : 33.3%
need a 3: (roll a 1, 2, 3): 50%

rolls of 4-6 are ignored

If you want to play around with https://anydice.com, this formula is for the
example given above 5d³(3):

output [count 3 in 5d{1, 2, 2, 3, 3, 3}]

Chances of each result (counting how many 3s you get):

0 "3s": 3.125%
1 "3s": 15.625%
2 "3s": 31.25%
3 "3s": 31.25%
4 "3s": 15.625%
5 "3s": 3.125%

Thank the heavens, it's always such a trouble to half the d6s to make d3s.

Preface: I genuinely have no intuition for probabilities

But it's not the same is it?

With the Thrice Dice (or with the standard d6 alternative), it is
describing an 3-in-6 (50%) chance, a 2-in-6 (33%) chance, and a 1-in-6
(16%) chance.

Halving a d6 wouldn't give you the same 122333 probability spread.

In any case, I like it. I think it's cute. The custom dice are pretty
neat, and it's also perfectly playable without them as well. I think
that versatility makes it a pretty clever system.

Should be 'failed' not ignored, though I guess it means the same thing.

Dice pools meh. You're making successes fairly average I guess which
while good for the players statistically, is not for good for fun, as I
learned with 4e's skill challenges.

I haven't played with dice pools very much, but I'm starting to think I'd
prefer playing in games were "this one die roll is critical" type play.
Rolling one die is more visible and can bring the whole table to watch and
react to that one roll.

I've still backed the kickstarter, cause "ohh new and shiny" always gets me :)
