Warhammer: The Old World is a different analytical challenge. Where AoS uses a skirmish-style activation system where individual units engage independently, The Old World is a game of ranked regiments, combined arms, and phase sequencing. The maths doesn't change — probability is probability — but the context in which damage is delivered and absorbed is fundamentally different.

The Old World introduces factors that AoS largely abstracts away. Weapon Skill against Weapon Skill, Strength against Toughness, rank bonuses, Leadership and the Break test all shape combat resolution in ways that have no direct equivalent in AoS. The Statshammer framework adapts to account for these — not by abandoning the core metrics, but by adding to them: Wounds₁₀₀ for damage, E₁₀₀ for durability, CE₁₀₀ for combat result including ranks, and the chance a unit breaks when it loses.

The USP for The Old World content is combat resolution modelling. Most players know ranks and Leadership matter. The Statshammer approach quantifies exactly how much: how much of a unit’s combat result comes from ranks rather than kills, how often a losing unit really runs, and when striking first actually saves a unit damage — which turns out to be when its enemy has no models to spare.

The Old World content is earlier in development than the AoS series, but the same analytical rigour applies. The framework is being built in the same sequence — baseline average unit, efficiency matrix, faction archetypes — with The Old World's specific mechanics incorporated at each stage. If you play The Old World and you're tired of relying on reputation to evaluate your regiments, this is the series for you.
