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

Optimization · Systems & Chaos
Medieval dynasty sim with chaotic event-driven stories.

Optimization · Pure Optimization
A turn-based strategy game where building the optimal army and economy decides victory.
Crusader Kings II leans Optimization (Systems & Chaos); Heroes of Might and Magic IV 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.
Crusader Kings II
pausable, no reflex
Heroes of Might and Magic IV
no real-time physical skill needed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crusader Kings II
AI characters scripted not adaptive
Heroes of Might and Magic IV
predicting human opponent strategy in PvP
Crusader Kings II leans a little harder on variance, though the gap is small.
Crusader Kings II
dynastic events, traits, intrigue
Heroes of Might and Magic IV
combat rolls and map resources random
Heroes of Might and Magic IV leans a little harder on optimization, though the gap is small.
Crusader Kings II
succession, marriages, claims plannable
Heroes of Might and Magic IV
army building and economy 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.
