I noticed -- but that still didn't make any sense. Now, percentile dice can be set to 00, but that usually indicates 100, not 0.
I know - this obviously wasn’t written by even a semi-nerd.
But, in 1974, when D&D was invented, and later in the 1970s, when Advanced Dungeons & Dragons became immensely popular, it was a unique form of entertainment made by intelligent outcasts for intelligent outcasts who previously had little or no foothold in popular culture.
I caught that as well. WTF?
Not true. The original 20 sided dice had 0-9 on them, twice. The 10-20 values were represented by a line under the numeral. Thus, a ten was a "0", and a twenty was a "0"
Ten sided dice (two of which make percentile dice) came later. Twenty sided dice were the original percentile dice with 0-9 repeated twice with one set colored in for the 11-20. I haven’t played in 20 years, but I was playing D&D since the days it was mail order only and was always addressed to “your name” sitting atop his castle at your address.
