are the books like the D&D books? is this just a dragon ball z verson of D&D?
The DBZ AAG uses 3d6 (3 six-sided dice) to determine skill checks and attack/evasion rolls. Damage is determined by rolling a number of d6's equal to the number. Ex: 10 damage = 10d6. Ex. 2: Kamehameha 2000 damage = 20d6 x 100.
Though I have found that rolling a single d2 for attacks and skill checks is a lot simpler than rolling 3d6 (where the lowest number is 3 and the highest is 18).
The gameplay doesn't use the d20 system, but the many different themes for your adventures are limitless. You could fight a powerful sorcerer in a dungeon, then fight his minions who seek revenge in the depths of space on a distant moon, or even as simple as keeping watch over a nest of bird eggs overhanging a waterfall in the middle of a storm! (Goku did that!)
Sadly my last batch of funds leave me without enough to make it to the con.

But there is hope! Those who were looking forward to playing should keep an eye out on both the MEW and Kumoricon forums for a DBZ meet I have planned sometime in late January.
