An updated edition of the original RPG Dungeons & Dragons, published by Wizards of the Coast (WotC). Based on the d20 system, this is the first new RPG system put out by WotC since they acquired TSR.
This is a major rewrite of the entire system compared to Advanced Dungeons & Dragons, Second Edition.
Going back to their roots and trying to streamline and improve the system they have made adjustments to all aspects of the system. From adding in popular house rules, combining similar rule sets into one mechanic, and abolishing artificial limitations placed on races and classes they have produced a much better game that its predecessor.
Succeeded by Dungeons and Dragons 3.5.
