In the game I made recently (Battlestreets), I used a dice pool mechanic, a basic “count 4-5 as successes, and 6s as double” with the idea that you build a power bar from the successes you accrue.
I still like that basic idea of using 6s as something special, then it occured to me, you could have a d5 system by rolling, say, 4d6, but remove the 6s – they count as 0 for the total but are kept as “power results” to build a resource bank. What’s left is a result from 0 - 20. What a sweet DnD-ish result with a nice bell curve!
I also like that 10 is the basic target number with a 55% chance a nice tier of difficulties at 12, 14, and 16,. (My attempt at Anydice here.) Unfortunately, if you use stat bonuses, you can only really get up to +3, as +4s will yeild almost a 90% chance rate, so it’s not as granular as I’d like it to be.
Still, I got excited enough about it that I wanted to share. Is it unrealistic to think that this might be a thing? Even if the 6s removed got to be a cool resource, for stunts, etc., I think a lot of people might balk at it being a bit unconventional.
