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
Era-typical console shooting skill across scripted spy missions and couch multiplayer.

Execution · Pure Mechanics
Squad shooting against scripted hordes with light class-loadout decisions.
James Bond 007: Nightfire 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.
James Bond 007: Nightfire
Console aim and gadget timing carry campaign and splitscreen
Resident Evil: Operation Raccoon City
Third-person aim against zombie and soldier swarms carries the game
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
James Bond 007: Nightfire
Splitscreen friends can be predicted; bots cannot
Resident Evil: Operation Raccoon City
Versus modes add human prediction; campaign AI is scripted
Resident Evil: Operation Raccoon City leans a little harder on variance, though the gap is small.
James Bond 007: Nightfire
Levels and AI behaviour are fixed and learnable
Resident Evil: Operation Raccoon City
Infection mechanics and spawn chaos add mild unpredictability
James Bond 007: Nightfire leans a little harder on optimization, though the gap is small.
James Bond 007: Nightfire
Route and gadget usage per mission is solvable
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.
