Warhammer Age of Sigmar: Complete Fantasy Wargame Guide

Warhammer Age of Sigmar isn’t just a new edition of an old game—it’s a complete narrative reset that replaced the world-ending End Times of Warhammer Fantasy Battle with the vast, magical Mortal Realms. This guide walks you through what makes Age of Sigmar tick, how it compares to 40k, and what you need to know as a beginner.

The pattern: Age of Sigmar replaced a setting with one world for a setting with eight, each with its own elemental identity.

What is the Warhammer Age of Sigmar?

The Setting of the Mortal Realms

The Mortal Realms are a chain of eight interconnected cosmic realms, each dominated by a different elemental force or magical wind. According to the Warhammer Age of Sigmar official site (game publisher), these realms are “a fantastical setting of myriad factions battling for supremacy.” Factions are sorted into four Grand Alliances: Order, Death, Chaos, and Destruction.

• Order includes armies like the Stormcast Eternals and Lumineth Realm‑lords.
• Chaos contains the Slaves to Darkness, Skaven, and Beasts of Chaos.
• Death covers the Nighthaunt, Flesh‑Eater Courts, and Ossiarch Bonereapers.
• Destruction brings Orruk Warclans, Gloomspite Gitz, and Sons of Behemat.

The implication: the Grand Alliance system makes it easy to find a thematic home—you don’t need to know every faction to pick a side.

Core Game Mechanics

Players build armies using pitched battle profiles, warscrolls, and battle traits. A standard 2000‑point list typically needs one leader and three battleline units, according to a beginner’s guide video (community tutorial). The game uses alternating activations and objective‑based scoring, with magic and combat playing a central role.

The trade‑off: simpler than Warhammer Fantasy Battle, but deeper than a casual skirmish game—perfect for players who want strategic weight without a rulebook the size of a phone book.

What is the difference between Warhammer and Age of Sigmar?

Setting and Lore

Warhammer Fantasy Battle was set in the Old World, a single continent based on Renaissance Europe. Age of Sigmar replaces that with the Mortal Realms—a cosmic playground where gods and monsters clash. The old game ended with the End Times narrative; Age of Sigmar is a fresh start.

Wargamer’s armies guide notes that many Warhammer Fantasy models were discontinued, though some are still usable with square bases in legacy formats.

Rules and Scale

Age of Sigmar uses round bases by default, whereas Warhammer Fantasy used square bases for ranked units. The ruleset is also lighter: no complex formations, no flank charges, and fewer charts. A game of AoS typically finishes in 2–3 hours, while older Warhammer games could stretch to 4+.

Model Lines

Many iconic fantasy units (Empire, Dwarfs, Bretonnia) were retired. In their place, new ranges like the Stormcast Eternals and Kruleboyz define the current aesthetic. According to a faction‑explainer video on YouTube (community content creator), Cities of Sigmar originally assembled models from multiple races and legacy kits.

The catch: if you already own a Warhammer Fantasy army, you can still play—but the game has moved on.

Is Age of Sigmar and 40k linked?

Shared Universe?

No. Warhammer Age of Sigmar and Warhammer 40,000 are set in entirely separate universes. Both are published by Games Workshop, but there is no narrative crossover. Occasionally you’ll spot an Easter egg—a reference or a similar unit name—but the rules, technology, and cosmology are distinct.

Wargamer’s guide confirms that faction lists and lore are kept completely separate.

Gameplay Differences

40k is a ranged‑heavy sci‑fi game with vehicles and psychic powers; Age of Sigmar is melee‑heavy fantasy with magic wizards and monsters. The core mechanics differ too—AoS uses a more streamlined activation system, while 40k has complex shooting phases and terrain rules.

The catch: despite sharing a brand, the two games require different tactical mindsets.

What is the difference between Age of Sigmar and 40k?

Theme and Setting

Age of Sigmar is high fantasy—think magic, dragons, and gods. Warhammer 40,000 is grimdark sci‑fi with space marines, aliens, and plasma guns. The Mortal Realms are mystical and colourful; the 41st Millennium is dark and industrial.

Factions and Units

AoS has about 24+ factions, from the angelic Stormcast to the crazed Goblin cults of the Gloomspite Gitz. 40k has around 20+ factions, but its army rosters include more vehicle and heavy weapon options. AoS units are generally more melee‑focused; 40k units rely on firepower.

Gameplay Complexity

Many players find Age of Sigmar more accessible because it has fewer special rules and modifiers. According to the beginner’s guide video (community tutorial), the core rules fit on a few pages, whereas 40k’s rulebook is thicker and layered with exceptions. The hobby commitment (building, painting, terrain) is similar.

The pattern: if you value streamlined play and epic fantasy, AoS pulls ahead. If you love tactical shooting and sci‑fi lore, 40k remains king.

Six points of comparison, one pattern: Age of Sigmar simplifies where 40k complicates, making it a gentler entry point into miniatures wargaming.

Is the Age of Sigmar easier than 40k?

Rule Complexity

Age of Sigmar’s core rules are indeed shorter. The current 4th edition streamlined further by introducing Spearhead, a faster game mode. According to the Wargamer guide (tabletop gaming news and guides), many players find AoS more accessible because it has fewer special rules and modifiers.

Unit Abilities

Warscrolls (unit datasheets) in AoS usually contain four to six abilities. In 40k, a datasheet can have ten or more, plus army‑wide stratagems. The cognitive load is lower in AoS.

Learning Curve

The hobby commitment (assembly, painting, terrain, list‑building) is roughly equivalent. But the tabletop gameplay itself—turn structure, objectives, charge and combat—is simpler to grasp. A beginner can play a meaningful game after one tutorial.

The trade‑off: easier does not mean shallow. AoS still rewards deep tactical thinking, especially around objective placement and magic timing.

Quotes from the community

“The Mortal Realms are a fantastical setting of myriad factions battling for supremacy.”

— Warhammer Age of Sigmar official site (game publisher)

“Stormcast Eternals are a central Order faction and one of the most obvious starting points for new players.”

— Wargamer (tabletop gaming news and guides)

For new players picking their first army, the choice comes down to what excites you: the thunder of Stormcast charges, the cunning of Skaven hordes, or the primal fury of the Orruk clans. The hobby investment is substantial—time, money, and patience—but Age of Sigmar rewards commitment with a rich narrative and a welcoming community. For the would‑be general in the UK or US, the implication is clear: start with a starter box that matches your vibe, learn the core rules in a few games, and then expand. Stick with the Spearhead mode for quicker battles, but the real victory is finding a faction you love to paint and play.
