The granddaddy of all CDGs. Despite its popularity, Dragon Dice didn't reach TSR's financial expectations and they discontinued the game after mass-advertising their new Treefolk expansion. Still, its success created 7 expansions which is more than most CCGs. A company called SFR bought out the license and finally released the much anticipated Treefolk kicker pack.
The game was sold as a Federation and a Borg starter set. Klingon and Romulan expansions were advertised in the rulebook but to the best of my knowledge none have ever materialized. Perhaps the Star Trek: Red Alert collectable disk game took priority?
I use the term "dice" loosely here since they are actually paper cubes that you fold together and assemble yourself. Definitely the cheapest components of all the CDGs which is rather appropriate since it's published by Cheapass Games.
I'm not sure how successful Rolled Bone was for its publisher D'Ice Inc. I do know that they created a technology to print directly on dice which eliminated the need for die-cast molds. I've seen these type of dice pop up in other games as alternatives for custom dice.
The Japanese version let you unfold your dice to create the dungeon map. This is a cool mechanic that simulates the T.V. show. Unfortunately the U.S. version just uses normal dice and you can freely choose your dungeon path. I much prefer this game over the Yu-Gi-Oh CCG though.
While this is basicly a kids' game it's still fun even for adults, especially when using the advanced 10 vs 10 rules. Always worth a shot in a lunch break or as fun game at a tavern. Due to lack of higher challenge for adults I consider it just a fun game for inbetween. Basic gameplay is a kind of mixture of Throwing Pigs and stuff like yu-gi-oh. (For the Germans on this BGG: It's a mixture of "Knobeln" and "Schweine Würfeln")It uses typical japanese yu-gi-oh-kind of fantasy characters and involves little strategy. Take a look!
