In general, a prototype isn’t nearly as nice as a finished product. That may end up not being the case for Rocket Dice. The prototypes shown in the Kickstarter promotions were 3D printed, which produces a much more consistent product than most dice manufacturing processes. Which Game Salute seems only now to be discovering.
There are more consistent dice manufacturing methods. They’re used for Casino dice and precision Backgammon dice. Those come only in six-siders and lack the fanciful shape of the Rocket Dice. They are also very expensive. Gamescience makes precision polyhedral dice, but they’re also more expensive than other polyhedrals. Especially when inked, because they have to be inked by hand. Game Salute says they are committed to deliver the “best dice possible”, but that’s likely to be a lot more expensive than they bargained for.
One thing in Rocket Dice’s favor is that the spur from the molding process could be located in a less obtrusive place than on Gamescience dice.
It will to be interesting to see what happens.
