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
Throttle and counter-steer precision on loose surfaces against the clock.

Execution · Pure Mechanics
A destruction-heavy racer where holding a line through flying debris is the core skill.
Colin McRae: Dirt leans Execution (Pure Mechanics); FlatOut leans Execution (Pure Mechanics).
Colin McRae: Dirt leans a little harder on execution, though the gap is small.
Colin McRae: Dirt
Car control on loose surfaces is the entire test
FlatOut
Car control through destructible chaos at speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae: Dirt
Racing the clock or AI lines, nothing adapts
FlatOut
AI racers don't adapt; multiplayer reads are shallow
FlatOut leans a little harder on variance, though the gap is small.
Colin McRae: Dirt
Surface grip and damage add mild run noise
FlatOut
Physics debris and crash chaos inject randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Colin McRae: Dirt
Setup tuning and corner-line knowledge underpin pace
FlatOut
Lines, upgrades, and nitro management are learnable
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.
