head to head
Kerbal Space Program asks more than Medieval II: Total War, and the gap is execution.

Optimization · Pure Optimization
Rocket engineering sandbox about orbital mechanics.

Optimization · Pure Optimization
Grand strategy wargame mixing turn-based empire play with real-time battles.
Kerbal Space Program leans Optimization (Pure Optimization); Medieval II: Total War leans Optimization (Pure Optimization).
Kerbal Space Program leans clearly harder on execution.
Kerbal Space Program
Manual piloting, docking precision
Medieval II: Total War
real-time battle micro is modest
Medieval II: Total War leans a little harder on reads, though the gap is small.
Kerbal Space Program
No adaptive opponents
Medieval II: Total War
campaign AI is exploitable and mappable
Medieval II: Total War leans a little harder on variance, though the gap is small.
Kerbal Space Program
Light reentry and physics variance
Medieval II: Total War
fog of war and event triggers hide some state
Kerbal Space Program leans a little harder on optimization, though the gap is small.
Kerbal Space Program
Rocket design, delta-v budget, mission planning
Medieval II: Total War
economy, unit counters, and campaign map strategy 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.
