head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, 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 melee-heavy sci-fi horror game where reactive parry timing and dodge reads dominate over system depth.
DiRT 4 leans Execution (Pure Mechanics); The Callisto Protocol 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
The Callisto Protocol
Melee-parry timing and dodge-direction choices are the core skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DiRT 4
Time-attack structure has no adaptive opponent
The Callisto Protocol
Mutants follow telegraphed scripted attack patterns
DiRT 4 leans a little harder on variance, though the gap is small.
DiRT 4
Procedurally generated stages prevent full route memorisation
The Callisto Protocol
Some loot containers and drop variability add mild uncertainty
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
The Callisto Protocol
Weapon upgrades and credit management have limited depth
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.
