 Combining NUELOW Games supplements with Troll Lord Games' Amazing Adventures (whether running the SIEGE Engine or the 5E variant) provides a unique framework for running pulp-adventure, weird fiction, retro-sci-fi, and horror campaigns. This blog post picks up from 

OSR Commentary - Using Neulow Games Supplements with The Amazing Adventures role playing game By Jason Vey

Because NUELOW Games specializes in public domain comic book/pulp sourcebooks, vintage public domain art, and d20-era/OGL rule tweaks—and Amazing Adventures is built specifically to handle multi-genre pulp and super-science—the two lines complement each other well.

1. Bridging the Systems & Rules Mechanics

NUELOW supplements frequently use early d20 System, OGL, or system-neutral formats, whereas Amazing Adventures uses either the SIEGE Engine (compatible with Castles & Crusades) or 5th Edition.

Integrating Attribute Checks & Saves (SIEGE Engine)

• Target Numbers & SIEGE Checks: NUELOW supplements often feature fixed d20 Skill DCs (e.g., DC 15 Search, DC 20 Disable Device). Convert these directly into SIEGE Engine Attribute Checks:

  • Prime Attribute: Base Target Number = 12 + Challenge Level (CL).

  • Non-Prime Attribute: Base Target Number = 18 + Challenge Level (CL).

  • Calculate the CL directly from the d20 DC: $\text{CL} = \text{DC} - 15$.

Converting Character Classes & Archetypes

• Pulp Archetypes: NUELOW’s character profiles (e.g., retro superheroes, hardboiled detectives, vigilantes) translate easily into Amazing Adventures classes:

  • Pugilist / Raider: Great for NUELOW’s brawling heroes or street-level vigilantes.

  • Mentalist: Maps directly to psychic heroes, brain-mind powers, and occult investigators.

  • Gadgeteer / Socialite: Ideal for pulp inventors, billionaire crime-fighters, or femme fatales.

• Fate Points Integration: Spend Amazing Adventures Fate Points to activate NUELOW’s dramatic comic-book stunts, auto-saves against doom, or narrative plot twists.

2. Best NUELOW Content for Amazing Adventures Genres

Weird War & Alternate History

• The Synergy: Amazing Adventures excels at gunfights, occult intrigue, and super-science. NUELOW offers detailed historical and public domain war comic adaptations.

• Implementation: Use NUELOW’s military sourcebooks to outline unit rosters, period gear, and historic event timelines. Run combat encounters using the Amazing Adventures auto-fire, burst, and suppression mechanics.

Cosmic Horror & Weird Fiction

• The Synergy: Integrating Lovecraftian horrors or Hodgson-style apocalyptic environments into Amazing Adventures.

• Implementation: Use NUELOW’s creature concepts or comic-based entity stats as monsters in SIEGE Engine terms. Combine NUELOW's horror themes with Amazing Adventures' Sanity / Madness and Psychic / Mentalist rules to model horror hazards.

Public Domain Heroes & Super-Syndicates

• The Synergy: NUELOW has adapted scores of Golden Age and public domain heroes, villains, and syndicates.

• Implementation: Convert NUELOW character concepts into Amazing Adventures NPC stat blocks:

  • Use Gadgeteer powers or Super Science items for gear-based heroes.

  • Use Mentalist powers for psychic abilities.

  • Treat comic-book super-villain organizations as major campaign factions using the SIEGE Engine's challenge rating framework.

3. Practical Conversion Cheat-Sheet

NUELOW / d20 Concept	Amazing Adventures (SIEGE Engine) Equivalent
d20 Skill Check (DC X)	SIEGE Check: $d20 + \text{Attribute Mod} + \text{Level}$ vs. $12/18 + \text{CL}$
Feats / Special Traits	Class Abilities, Background Benefits, or Fate Point Stunts
d20 Defense / AC	Armor Class (Base 10 + Dex + Armor)
Reputation / Action Points	Fate Points (replenished per level or key milestone)
Sanity / Morale Loss	Wisdom / Charisma SIEGE Check vs. Terror Hazard CL

4. GM Workflow for Running a NUELOW Campaign

1. Setting the Stage: Use NUELOW's retro-art panels, adventure seeds, and historic background text for world-building and player handouts.

2. Stat Block Conversion: For monsters or NPCs, keep NUELOW’s hit points and narrative flavor, but assign SIEGE Prime Attributes (e.g., Physical or Mental) and compute a Challenge Level (CL) based on character/monster level.

3. Pacing Combat: Use Amazing Adventures' fast-paced SIEGE resolution to handle the tactical action, pulpy brawl combat, and automatic weapon fire, preserving NUELOW’s comic-book storytelling tone.

Using NUELOW Games’ Golden Age Super Heroes line with Troll Lord Games’ Amazing Adventures (SIEGE Engine) provides a streamlined way to run classic 1930s–1940s comic book heroism.

NUELOW’s Golden Age titles—such as Complete Golden Age Oddballs (featuring obscure heroes like Fireman, Major Victory, Yankee Girl, or Stardust), Madden’s Boys, Wildfire, and The Original Peacemaker—combine curated public-domain comic reprints with d20/OGL mechanical adaptations.

Amazing Adventures was designed explicitly for pulp, weird science, and street-level to mid-tier superheroics. Translating NUELOW’s Golden Age superhero content into the SIEGE Engine framework allows you to run campaigns with authentic WWII-era pulp flavor.

1. Adapting Superhero Archetypes & Classes

NUELOW’s Golden Age characters usually fit into distinct superhero archetypes that map directly into Amazing Adventures classes:

Golden Age Hero Type (NUELOW)	Amazing Adventures Class	SIEGE Engine Primary Attribute	Core Mechanics & Powers
Mystery Men / Vigilantes (e.g., The Eye, Daredevil)	Gumshoe or Hooligan	Strength or Dexterity	High martial arts skills, streetwise stealth, stealth/brawling feats
Patriotic Soldiers (e.g., Major Victory, Yankee Girl)	Raider or Pugilist	Strength or Constitution	Super-strength, high Hit Dice, high melee output
Super-Science Inventions (e.g., Volton, Dynamic Boy)	Gadgeteer	Intelligence	Uses Amazing Adventures super-science/gadget creation rules to model power suits or energy weapons
Mystic / Cosmic Entities (e.g., Wildfire, Stardust, Fantomah)	Mentalist or Sorcerer	Wisdom or Charisma	Uses the Amazing Adventures psionics/magic system re-skinned as cosmic or elemental powers

2. Converting NUELOW d20 Stats to SIEGE Engine

NUELOW supplements use OGL/d20 stat blocks. To convert these for Amazing Adventures:

Target Numbers & Attribute Checks

• NUELOW d20 Skill DCs convert straight into SIEGE Engine Challenge Levels (CL):

  $$\text{Challenge Level (CL)} = \text{d20 DC} - 15$$

• Primary Attribute SIEGE Check: Target Class = $12 + \text{CL}$

• Secondary Attribute SIEGE Check: Target Class = $18 + \text{CL}$

Converting Superpowers

Rather than tracking granular d20 spell-like abilities, use the Fate Point & Power System in Amazing Adventures:

• Inherent Powers (Flight, Super-Strength): Treat as class abilities or spend 1 Fate Point to gain temporary structural feats (e.g., lifting tanks, surviving explosions).

• Gadgets & Gimmicks: Use the Amazing Adventures Gadgeteering framework, treating NUELOW’s magic rings, ray guns, or armored suits as spell-effect devices powered by charges or battery limits.

• Vulnerability & Weaknesses: Golden Age heroes often had quirky vulnerabilities (e.g., losing powers if bound by wood/rope or running out of sunlight). Award characters an extra Fate Point whenever their specific character flaw actively complicates the plot.

3. Campaign Themes & GM Setup

1. WWII Axis Super-Villainy & Axis Occultism

NUELOW’s Golden Age titles frequently feature Axis spies, mad scientists, and bizarre occult threats.

• Integration: Use NUELOW’s public-domain villains as main threat factions. Run squad-scale battles using Amazing Adventures' fast-paced combat and burst/automatic fire rules.

2. Weird Science & Cosmic Horror Overlays

Golden Age comics were notorious for jumping from street-level muggings to surreal, alien cosmic landscapes (e.g., Stardust the Super-Wizard).

• Integration: Use Amazing Adventures' optional Sanity and Madness rules alongside Lovecraftian elements when heroes encounter cosmic threats or extraterrestrial super-science.

3. Comic Book Narrative Pacing

Golden Age comic stories were fast, episodic, and punchy.

• Over-the-Top Heroics: Grant players 3–5 Fate Points per session to encourage dramatic comic-book maneuvers (e.g., throwing cars, leaping across rooftops, catching falling bombs).

4. Quick Conversion Example: Wildfire (Carol Vance)

• NUELOW Concept: Blessed by the Lord of Fire, capable of manipulating and projecting flame.

• Amazing Adventures Adaption:

  • Class: Mentalist (Pyrokinesis build) / Sorcerer re-skinned.

  • Prime Attributes: Charisma, Dexterity, Constitution.

  • Core Powers: Flame Blast (range attack, $d6/d8$ elemental damage), Fire Shield (+2 AC vs. physical, immunity to fire), Flight (bursts of fiery propulsion).

  • SIEGE Check Hook: Dexterity SIEGE Check ($12 + \text{CL}$) to manipulate environmental fire (e.g., melting steel doors or extinguishing blazes).
