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
Grand strategy wargame mixing turn-based empire play with real-time battles.

Optimization · Pure Optimization
A castle-building strategy game where economic optimization and defense planning is the whole test.
Medieval II: Total War leans Optimization (Pure Optimization); Stronghold 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.
Medieval II: Total War
real-time battle micro is modest
Stronghold
minimal, mostly clicking and management
Stronghold leans a little harder on reads, though the gap is small.
Medieval II: Total War
campaign AI is exploitable and mappable
Stronghold
AI opponents are scripted, minor prediction
Medieval II: Total War leans a little harder on variance, though the gap is small.
Medieval II: Total War
fog of war and event triggers hide some state
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.
Medieval II: Total War
economy, unit counters, and campaign map strategy dominate
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.
