head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Throttle and counter-steer precision on loose surfaces against the clock.

Execution · Pure Mechanics
A twin-stick run-and-gun shooter testing aim and dodging against enemy waves.
Colin McRae: Dirt leans Execution (Pure Mechanics); Wolf of the Battlefield: Commando 3 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.
Colin McRae: Dirt
Car control on loose surfaces is the entire test
Wolf of the Battlefield: Commando 3
Twin-stick aiming and dodging under heavy fire leads
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae: Dirt
Racing the clock or AI lines, nothing adapts
Wolf of the Battlefield: Commando 3
Enemies spawn in scripted waves, not adapting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae: Dirt
Surface grip and damage add mild run noise
Wolf of the Battlefield: Commando 3
Spawn timing adds minor unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae: Dirt
Setup tuning and corner-line knowledge underpin pace
Wolf of the Battlefield: Commando 3
Weapon and position management is a light 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.
