I am strongly considering using some kind of narrative dice system for Space Hex.
What I like is that you end up building a dice pool to resolve an action where the d6 represents luck, a d8 represents attributes, and a d12 represents skill and this is opposed by a d6 that represents luck, a d8 that represents difficulty, and a d12 that represents a technical difficulty.
Then you have symbols for success and failure, threat and advantage, as well as triumph and despair.
So a dice pool goes beyond hitting a target number and enters the realm of explaining how a situation unfolds.
A threat can be another enemy enters the room and success from luck can mean a lucky shot.
What I don’t like is buying specialty dice seems like a cash grab, especially when people use them in the same fashion as a target number.
