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
Unforgiving boat-handling execution across 25 memorisable scripted trials.

Execution · Pure Mechanics
A rally racer where mastering precise car control against tricky terrain is everything.
Cobra Triangle leans Execution (Pure Mechanics); Colin McRae: Dirt 2 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.
Cobra Triangle
Boat handling on auto-scrolling water punishes every slip
Colin McRae: Dirt 2
precise rally driving and braking required
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cobra Triangle
Hazards and enemies follow fixed Rare-designed scripts
Colin McRae: Dirt 2
no adaptive opponents, mostly time trials
Colin McRae: Dirt 2 leans a little harder on variance, though the gap is small.
Cobra Triangle
Courses are identical on every attempt
Colin McRae: Dirt 2
weather and surface conditions vary
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cobra Triangle
Power-up routing and objective knowledge smooth the gauntlet
Colin McRae: Dirt 2
car tuning and racing lines solvable
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.
