TNU has a great hook for dungeon delving with its "Nightmare Incursions", hey better kill those dungeons before they unhinge reality and all that. The art and layout does a fantastic job of conveying the tone of the system. The system itself is fun, simple enough to get a hang of quickly but has enough there to satisfy further exploration. The added downtime and town/city systems add more depth for long-form campaigns. The classes are unique and complement the setting. Overall, a fun, unique twist on the D&D type game with a great vibe and new ideas that any GM would definitely want to steal for their own games (which I mean as a compliment).
