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.

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

Execution · Pure Mechanics
Squad shooting against scripted hordes with light class-loadout decisions.
Lost Planet: Extreme Condition leans Execution (Practiced Mastery); Resident Evil: Operation Raccoon City 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
Resident Evil: Operation Raccoon City
Third-person aim against zombie and soldier swarms carries the game
Resident Evil: Operation Raccoon City leans a little harder on reads, though the gap is small.
Lost Planet: Extreme Condition
Multiplayer modes add some mind games
Resident Evil: Operation Raccoon City
Versus modes add human prediction; campaign AI is scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Lost Planet: Extreme Condition
Campaign encounters are fixed
Resident Evil: Operation Raccoon City
Infection mechanics and spawn chaos add mild unpredictability
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
Resident Evil: Operation Raccoon City
Class abilities and loadouts are a shallow solvable layer
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.
