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

Optimization · Pure Optimization
A WWII grand strategy testing production planning and front-line logistics at scale.

Optimization · Pure Optimization
A castle-building strategy game where economic optimization and defense planning is the whole test.
Darkest Hour: A Hearts of Iron Game leans Optimization (Pure Optimization); Stronghold leans Optimization (Pure Optimization).
Stronghold leans a little harder on execution, though the gap is small.
Darkest Hour: A Hearts of Iron Game
Pausable map clicking, zero twitch demand
Stronghold
minimal, mostly clicking and management
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Darkest Hour: A Hearts of Iron Game
Multiplayer diplomacy adds rare human prediction
Stronghold
AI opponents are scripted, minor prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Darkest Hour: A Hearts of Iron Game
Historical events fire semi-randomly but are well documented
Stronghold
minor resource and raid randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Darkest Hour: A Hearts of Iron Game
Production, supply and front planning across decades is everything
Stronghold
economy and castle-building near-solvable
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.
