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 · Pure Mechanics
A rally sim whose procedural stages keep variance alive while rewarding clean car control.

Execution · Pure Mechanics
A test of fast, precise shooting and map navigation against scripted but relentless enemies.
DiRT 4 leans Execution (Pure Mechanics); Doom (1993) 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.
DiRT 4
Procedural stages still demand consistent throttle and apex discipline
Doom (1993)
Precise movement and shooting against relentless enemy pressure
DiRT 4 leans a little harder on reads, though the gap is small.
DiRT 4
Time-attack structure has no adaptive opponent
Doom (1993)
Enemies follow scripted patrol and attack patterns, not adaptive
DiRT 4 leans a little harder on variance, though the gap is small.
DiRT 4
Procedurally generated stages prevent full route memorisation
Doom (1993)
Enemy placement is fixed but unknown on first run through levels
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DiRT 4
Car choice, setup and rally team progression are solvable systems
Doom (1993)
Level routing and resource management determine survival efficiency
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.
