Highlights
Detailed domain and kingdom management rules, economics and mercantile systems are integrated throughout, mass combat scales from skirmishes to wars, 18 classes with quick-start templates, builds on B/X foundations
Considerations
540+ page rulebook is intimidating, tightly coupled subsystems, fantasy-only with narrow genre support, very high GM prep for domain-level play
