The dice that I thought might be the best choice is the brown 6-sided *number* dice, the next to be unlocked, for using as a score counter. Would 6 be the highest # of points you'd need to keep track of? (later dice go up to higher numbers....)
I pledged for a set of six red w/ the pips and if it makes it to the rpg dice I will get a set of those as well. Mainly got the d6's to spice up farkle.
