I've recently learnt about CthulhuTech, which has a unique dice pool system:
CthulhuTech uses a proprietary game system known as "Framewerk" that focuses on a dice pool system. An unusual feature is the selection of numbers from the d10 rolls – a player can pick a single highest number, all like numbers, or straights of consecutive numbers, and use these to generate the result. The result is then added to a "base" consisting of a related attribute score bought by the player at character creation. The sum of the base and the result is then compared to target numbers or to the results of an opponent's rolls to determine success or failure.
So for instance a roll of 1,2,3,4,5,5,10
the player could pick either 1,2,3,4
, 5,5
or 10
to add to their base score for a dice roll, before comparing it to the target number.
As a future game designer, I'd like to understand what sort of probability curve this creates for a given set of dice pool sizes, say 1-10 dice. This will hopefully let me see if I want to incorporate a similar dice pool system into a game I am planning.
