In Age of Sigmar, each of the different armies (now called factions) are a part of one of the four Grand Alliances. It is possible to field an army with models from the different factions within the same grand alliance, although it might not be the strongest army you can field. In Warhammer: Fantasy this would have been called ” mixing armies”. In my last game against a friend (he played Bonesplitters) my list was: Allegiance: Cities of Sigmar: Hallowheart. LEADERS. Freeguild General (100) - General - Veteran of the Blazing Crusade. Battlemage (110) - Mortal Realm: Ulgu (and 2 spells from Hallowheart) Battlemage (110) The Age of Sigmar is the name of the Great Epoch that marks the current historical era of the Mortal Realms and began with the return of the Ascended god Sigmar and the forces of his Stormcast Eternals to the Eight Realms during Sigmar's Tempest. Early in the Age of Chaos, the God-King Sigmar was forced to retreat from the Mortal Realms and seal off Azyr following the loss of the forces of Happy wargaming! We have another tier list for all of the armies in age of sigmar (RIP Legions of the First Prince). As always these lists are my own persona A big part of that is due to how broad and narrow some of the factions are in AoS. You can find some good stuff to build a warband of dwarfs, empire, some sort of elven faction, orcs, and undead. Those are kind of basic fantasy races. You will not find anything related to kharadon overlords, bonereapers, or other highly stylized IPs. There’s a lot going on with the transition to Age of Sigmar 3.0. These articles cover the basics of starting an army, getting into the game’s rules, and understanding the basics of Age of Sigmar. Age of Sigmar 3.0 First Impressions Roundtable; AoS 3.0 Rules Review; Editorial: No, you do not need the latest Chapter Approved or GHB Once Warhammer Age of Sigmar: The App has been released in full, all of its premium features will be included in your Warhammer+ subscription. In fact, you’ll get access to the apps for both Warhammer Age of Sigmar and Warhammer 40,000, on top of premium video series from Warhammer TV, the eye-popping new Warhammer Animations, the Warhammer The Twin-Tailed Crusade has plenty of ground left to cover in Dawnbringers book IV: The Mad King Rises and beyond – especially now that Neferata’s supernal serpent has slithered into the picture – and the Summerking’s shining court is only one of the challenges that await in 2024. Armies to avoid are: - Ossiarch (they have different rules and dont intereact with core elements of the game) - Cities of Sigmar (way too many possibilities) - Lumineth (too complex) - Sylvaneth (complex, but mostly cause you gotta bring a ton of gd trees) From the ones you listed, I'd say StD is probably the easiest. Age of Sigmar offers more grandeur and dynamic models out of the two, with the build quality being excellent and plenty of the models not requiring glue to assemble. As Warhammer 40k is the older system, Games Workshop is slowly updating its older models, with Black Templars being the latest Space Marine chapter to receive a rehaul and an UJsXMlz.
