head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
A classic Contra-style run-and-gun about precise reflexes and firepower.

Execution · Pure Mechanics
A hand-animated revival of Rayman's 2D platforming.
Operation C leans Execution (Pure Mechanics); Rayman Origins leans Execution (Pure Mechanics).
Operation C leans a little harder on execution, though the gap is small.
Operation C
precise run-and-gun reflexes and dodging
Rayman Origins
Fluid run-jump-glide chains
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Operation C
scripted enemy patterns, no adaptation
Rayman Origins
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Operation C
minimal randomness
Rayman Origins
Deterministic levels
Rayman Origins leans a little harder on optimization, though the gap is small.
Operation C
weapon pickup routing knowledge
Rayman Origins
Lum routing for perfection
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.
