Games Workshop runs two flagship tabletop miniatures systems side by side, and both draw serious collector followings, but Warhammer 40,000 and Age of Sigmar sit in genuinely different settings with different army-building philosophies. Picking between them shapes years of future purchases.
Warhammer 40,000 is set in a grim-dark science fiction future, built around space marines, xenos armies, and gothic sci-fi aesthetics. Age of Sigmar is a high-fantasy setting instead, with realms of magic, gods, and monstrous armies replacing 40K's tanks and starships.
Here's how the two actually compare for a collector deciding where to start building an army. Both systems have run for decades under Games Workshop, giving each an enormous back catalog of factions, box sets, and codexes to choose from.
Warhammer 40,000's grim-dark science fiction setting appeals to collectors drawn to gothic sci-fi, power armor, and vast interstellar warfare. Its factions range from the Imperium's space marines to alien Tyranids and Necrons, each with a distinct sculpted identity.
Age of Sigmar leans fully into high fantasy, with armies built around magic, mythic creatures, and god-touched warriors rather than starships and bolters. Its factions include Stormcast Eternals, Orruk Warclans, and undead legions with a more painterly, mythological sculpt style.
Collectors drawn to science fiction and military aesthetics tend to gravitate toward 40K, while those who prefer fantasy monsters and mythic armies tend to land on Age of Sigmar.
Both systems use similar model scales and modular kit design, so the actual hobby skills, painting techniques, and assembly experience transfer well between them. A collector comfortable building a 40K army won't face a steep learning curve moving into Age of Sigmar.
Army list construction differs meaningfully though, since 40K tends to emphasize ranged weapons and vehicle support, while Age of Sigmar leans more into melee combat and magic-based abilities. That difference shapes which faction playstyles feel most rewarding.
Starter box sets exist for both systems and remain the most cost-effective way to build a first army, typically bundling enough models and rules to start playing right out of the box.
Collectors who want a science fiction setting with vast interstellar scope and gothic military aesthetics tend to find 40K the more natural fit, especially given its larger overall player base and broader third-party support ecosystem.
Collectors who prefer high fantasy, mythic creatures, and a more painterly army aesthetic tend to prefer Age of Sigmar, which has built its own dedicated competitive and hobby community distinct from 40K's.
Some collectors build armies in both systems over time, since Games Workshop's shared production quality and modular kit design make switching between them a matter of preference rather than a steep new skill investment.
Both systems receive frequent new releases, codex updates, and expanded factions, meaning neither is at risk of running out of new models to collect regardless of which one a new hobbyist picks first.
Secondary-market demand for out-of-production kits exists in both systems, though 40K's larger player base generally means slightly stronger resale interest on discontinued models.
Community size also factors in: 40K's larger overall following means more local gaming groups and events in most regions, while Age of Sigmar's community, though smaller, remains active and dedicated in areas with established fantasy gaming scenes.
Both systems reward the same core painting and modeling skills, from priming and base coating through detail work and basing, meaning time invested learning to paint one army carries over directly to the other.
Games Workshop supports both systems with official paint lines, tutorials, and hobby guides, so new painters in either system have access to the same level of manufacturer support regardless of which they choose first.
Long-term collectors often find that owning painting tools and supplies compatible with both systems makes switching between 40K and Age of Sigmar projects, or running both simultaneously, more practical than it might first appear.
Local game stores remain the best place to see both systems' models in person before committing to a purchase, and many run demo games that let new hobbyists try each system's ruleset firsthand.
Online forums and painting communities dedicated to Games Workshop products are active and welcoming to beginners, offering feedback on both technique and army list building regardless of which system you choose.
