One of the items that gets used in every game but does not get talked about very much are dice.
There are ways of getting a large amount of cheap dice. Like the game Tenzi. This game features four sets of ten dice in colors that can be used in MFZ. It was brought to my attention by Otami N71.
Then there are specialty dice.
Such as these Lego dice by Eric Harshbarger.
These were brought to my attention by Daniele Grillezoni on Google+.
There are other specialty dice that I like. Such as the Q-Workshop Cyber Dice and the Q-Workshop Chip Dice.
There is one major problem with specialty dice though, no matching d8s.
