Gamers can be an oddly conservative bunch. They get into a specific routine, and any change to that is met with hostility. Many gamers are pretty adaptable, but the ones who aren't will often make their displeasure known.
My recent observation on this is how gamers generate a number from 1 to 100. If you don't already know this, it's been established since at least the '70s that you can generate this number with two ten-sided dice (d10). You declare a die as the tens digit and the other as the ones digit. Whatever you roll in the tens digit, you multiply by 10. Then you add the other die. But there are a couple of tricks that we use.
First, when rolling 1-100, the 10 on the die actually counts as a 0. Most d10s on the market are printed this way. It is actually a source of bemusement among new players when they roll the d10 and proclaim they got a 0 and not a 10. So, for example, a roll of 8 and 4 becomes 84. A roll of 0 and 6 becomes 06. And a roll of 2 and 0 becomes 20. This gives a range of 00 to 99, so any roll of 00 is counted as 100.
It's a bit convoluted, but it works. You have an even distribution of 1through 100.
Fast forward to around 1992 (the earliest I've heard someone claim he had one) and the introduction of the percentile dice. This is a pair of d10s, but one of them is numbered differently. Instead of 0, 1, 2, it is numbered with 00, 10, 20. The idea being that you no longer declare the tens digit. It's already established by this die. You roll a 20 and an 8, and it's 28. But the rule of 0 still applies, so 30 and 0 gave you 30, while 00 and 0 gave you 100. New players could especially be confused if they roll 10 and 0 and are told that is not indeed 100.
It occurred to me that you don't need to use that method with the percentile dice. Instead, you could take the dice at face value. First off, you have to acknowledge that the 0 on a d10 represents 10. In most games, that counts as a 10, but for 1-100, people tend to automatically think of it as 0. Of course, if the die is printed with a 0, that makes the shift easier. For a d10 that is printed with a 10, then adding the dice works pretty well.
And this is where the clash with traditional gamers happens. Because now I no longer view the dice as 40 and 0. Now I view them as 40 and 10, which is actually 50 and not 40. I don't have to mentally switch from 10 to 0 or from 00 to 100. I can roll as low as 00 and 1 (for 1) and as high as 90 and 10 (for 100). The vitriol is alarming, even by internet standards. It produces a range of 1 through 100 evenly distributed, but because it wasn't in a way that people first learned (and I have 30+ years of that habit in me), some people have taken offense.
