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.

Execution · Practiced Mastery
Frozen-planet shooter about managing heat while gunning down giant bugs.

Execution · Pure Mechanics
Era-typical scripted WWII shooting galleries testing aim and placement memory.
Lost Planet: Extreme Condition leans Execution (Practiced Mastery); Medal of Honor: Rising Sun leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Planet: Extreme Condition
Grapple movement and Akrid weak-point shooting
Medal of Honor: Rising Sun
Aim against scripted soldier placements is the core demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Planet: Extreme Condition
Multiplayer modes add some mind games
Medal of Honor: Rising Sun
Multiplayer adds light human prediction; campaign AI is static
Lost Planet: Extreme Condition leans a little harder on variance, though the gap is small.
Lost Planet: Extreme Condition
Campaign encounters are fixed
Medal of Honor: Rising Sun
Setpiece missions replay identically
Lost Planet: Extreme Condition leans a little harder on optimization, though the gap is small.
Lost Planet: Extreme Condition
Thermal energy management and boss weak points
Medal of Honor: Rising Sun
Memorising enemy placements and routes is shallow but present
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.
