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 demolition racing game where causing crashes scores points and your own car degrades realistically.

Execution · Pure Mechanics
A rally sim whose procedural stages keep variance alive while rewarding clean car control.
Destruction Derby 2 leans Execution (Pure Mechanics); DiRT 4 leans Execution (Pure Mechanics).
DiRT 4 leans a little harder on execution, though the gap is small.
Destruction Derby 2
Surviving and steering through wreck-strewn packs takes skill.
DiRT 4
Procedural stages still demand consistent throttle and apex discipline
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Destruction Derby 2
AI drivers crash by script, not adaptation.
DiRT 4
Time-attack structure has no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Destruction Derby 2
Pile-ups and damage cascades are highly unpredictable.
DiRT 4
Procedurally generated stages prevent full route memorisation
DiRT 4 leans a little harder on optimization, though the gap is small.
Destruction Derby 2
Targeting hits for points and protecting the radiator is learnable.
DiRT 4
Car choice, setup and rally team progression are solvable systems
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.
