I'm fine-tuning the dice mechanics for my game, and I thought I'd ask how people felt about different ways of using Dice.
What do you think about using Polyhedral dice (those weird d&d dice) in games? If the game calls for anything other than regular 6-sided dice, is it better to limit the types used (perhaps just d6 + d20) or try and ensure a wide range of dice get used in actual gameplay (d4, d6, d8, d10, d12, d20)?
Generally (and momentarilly ignoring statistical differences in the results), Is it better* to ask a player to do some math to modify the result of their dice roll, or is it better to ask them to roll a different kind of dice?
eg. d20-8 OR d12 OR 2d6
If you ask them to do some math, is it better* to ask them to add and subtract numbers from the result, or better just to use addition and turn any subtraction into an addition for the opposing dice roll?
eg. d6+2-1 vs d6 OR d6+2 vs d6+1
* Better = is one more fun than the other? Or does it make little difference?
Any other thoughts on dice? How often and how many do you like to see rolled in a game? Anything you really like or dislike about using dice? Any games that do it really well or really poorly?
