The 4th Edition of Dungeons & Dragons is largely incompatible to all previous versions. It keeps the d20 mechanic of the 3rd Edition, but character creation, the magic system and combat have been revamped. The focus of the rules lies on tactical combat, heavily recommending the use of miniatures. The German edition was published by Feder & Schwert, but production ceased after the release of the three core books due to licensing problems.
