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 · Pure Optimization
3D revival of the classic turn-based strategy formula with deep faction skill trees.

Optimization · Pure Optimization
A grand strategy 4X where empire optimization carries you through random crises.
Heroes of Might and Magic V leans Optimization (Pure Optimization); Stellaris 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.
Heroes of Might and Magic V
No dexterity component
Stellaris
Real-time pausable with no input precision.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Heroes of Might and Magic V
Only human opponents adapt
Stellaris
AI is scripted; multiplayer adds modest adaptation.
Stellaris leans a little harder on variance, though the gap is small.
Heroes of Might and Magic V
Fog of war, skill rolls, and morale
Stellaris
Galaxy gen, anomalies, and crises vary widely.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Heroes of Might and Magic V
Faction build orders and initiative math dominate
Stellaris
Empire builds, fleet comps, and economy dominate.
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.
