I have gotten my 5 year old son two of the LEGO Heroica sets recently. Information about the rules and products can be found at the Heroica web site. One of the coolest things about these sets is the included dice. Of course, you have to assemble them before use and I believe that you can also buy other faces to put on the dice; that makes for complete customization. The dice are approximately twice as big as the standard dice found in most board games.
Anyway, I just really dig these sets because it is a minimalistic version of fantasy adventure gaming rules that also encourage house ruling. That got me to thinking about the dice. I wonder what kind of tables or resolution systems could be designed around these special dice? I may explore that in the future but I just wanted to point this out as food for thought. If anyone has done this or knows of a site that has this information that I can mied for ideas, feel free to speak up!
