Is it too late to talk about the weird dice? :-)
I can certainly grok having fun with crazy new kinds, even if they may be a marketing gimmick in the case of DCC. I can also see that if there's a random resolution with, say, 5 or 7 options that will be rolled a lot (not just once in a blue moon), it's probably worth it to have an honest-to-goodness d5 or d7 around, instead of rolling a d6 or a d8 and treating the highest number as a gentle reminder to "roll again." Or using a handy conversion chart.
(Full disclosure: Right now in the draft player's guide of Homebrew '82, there is a table in the character generation chapter that calls for a d7. But it's the result of pure laziness! If and when I think of one more entry to add, it will be changed to a d8!)
But these farkakte shapes?
I should admit, of course, that I have no valid reason to doubt that these dice are statistically "fair." Lou Zocchi has patented the above d5, he has said a lot to justify the high quality of these dice, and Jeff Rients did some additional digging to find out that Zocchi's sales pitches do have lots of truth behind them. It's just that the physics geek inside me cringes when I see those non-isotropic shapes. Is Pythagoras rolling over in his equal-angled grave...?
