head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
Beautiful 19th-century city-builder ruled by production ratios.

Optimization · Pure Optimization
A WWII grand strategy testing production planning and front-line logistics at scale.
Anno 1800 leans Optimization (Pure Optimization); Darkest Hour: A Hearts of Iron Game leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1800
pausable, no twitch
Darkest Hour: A Hearts of Iron Game
Pausable map clicking, zero twitch demand
Darkest Hour: A Hearts of Iron Game leans a little harder on reads, though the gap is small.
Anno 1800
AI scripted, not adaptive
Darkest Hour: A Hearts of Iron Game
Multiplayer diplomacy adds rare human prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1800
minor trade fluctuations
Darkest Hour: A Hearts of Iron Game
Historical events fire semi-randomly but are well documented
Anno 1800 leans a little harder on optimization, though the gap is small.
Anno 1800
supply chains and ratios are the game
Darkest Hour: A Hearts of Iron Game
Production, supply and front planning across decades is everything
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
