I saw a game recently which used your typical mechanic where you roll a bunch of dice and count successes. This game used d8s, instead of d6s or d10s.
The interesting thing was, instead of saying that a roll of 6 or 7 counted as a success, and a roll of 8 counted as two successes; it said that a 6 or 7 was a success, and an 8 was also a success, but if you rolled an 8 then you also rolled two more dice, which could also be failures or successes, or could also be an 8 that was a success where you rolled two more dice, and so on.
The part that wasn't immediately intuitive to me, was what the average success rate is supposed to be. If I'm rolling ten dice, how many successes should I expect?
With something like Exalted, you roll d10s and 7 through 10 is a success, but a 10 is two successes - you roll ten dice, you'll probably get five successes. This system is more complicated than that, and I'm just not seeing where the math ends up. Is it the same? Do you average out to rolling a number of successes equal to half the number of dice being rolled?
