Yeah it's more about the visual feedback you get, because it does tend to roll around more. So even if an algorithm determines the face and the spinning and rolling is just smoke and mirrors, sometimes you want the smoke and mirrors. I always take bad dice rolls personally. They hate me for some reason, and I hate them. They have cost me many fine victories over the years. I'm like that unmasked villain of every Scooby-Doo episode. "I would have won if not for my poor dice rolls!" Irrational? Sure. But to quote Star Trek IV, "Who ever said humans were logical?"

Dice are set to a random face before physics set in, so they're totally random even if they don't roll. But rolling dice are far more satisfactory :) I love my 12-sided d4 dice IRL!
