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 castle-building strategy game where economic optimization and defense planning is the whole test.

Optimization · Pure Optimization
Industrial-era economy sim; pops and markets above all.
Stronghold leans Optimization (Pure Optimization); Victoria 3 leans Optimization (Pure Optimization).
Stronghold leans a little harder on execution, though the gap is small.
Stronghold
minimal, mostly clicking and management
Victoria 3
no reflex
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Stronghold
AI opponents are scripted, minor prediction
Victoria 3
AI scripted, limited adaptation
Victoria 3 leans a little harder on variance, though the gap is small.
Stronghold
minor resource and raid randomness
Victoria 3
events, market shocks
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Stronghold
economy and castle-building near-solvable
Victoria 3
economy, pops, laws 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.
