>>5166239Ah I see what you mean, it can feel a bit awkward. It comes down to personal preference really, but I always instinctively think of d100 as 00-99 not 1-100 here. You can obviously interpret the dice range however you want but in some of the games I used to play with the 00-99 range so rolling the 100 percentile d10 result was bad lol. Also if you do programming it makes some things easier to start 0-99 as opposed to 1-100, arrays start at 0, arr[0] etc, if you program random number generators and stuff it may make sense.
