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
Pure car control over loose surfaces, sharpened by memorising every stage.

Execution · Pure Mechanics
Push-forward arena FPS where movement and aim are the whole game.
Colin McRae Rally 2.0 leans Execution (Pure Mechanics); DOOM (2016) 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 Rally 2.0
Surface-specific car control at speed decides every stage
DOOM (2016)
Aim, movement, glory-kill timing all peak.
DOOM (2016) leans a little harder on reads, though the gap is small.
Colin McRae Rally 2.0
Time-trial format - no adaptive opponent on the stage
DOOM (2016)
Demons scripted attack patterns.
Colin McRae Rally 2.0 leans a little harder on variance, though the gap is small.
Colin McRae Rally 2.0
Mid-stage surprises minimal once pace notes are internalised
DOOM (2016)
Minimal encounter randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae Rally 2.0
Memorising stages and tuning setups converges times steadily
DOOM (2016)
Rune and weapon mod picks meaningful.
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.
