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 portable Tetris entry with varied modes atop the classic falling-block formula.
DiRT 4 leans Execution (Pure Mechanics); Tetris: Axis 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
Tetris: Axis
fast precise piece placement and rotation
DiRT 4 leans a little harder on reads, though the gap is small.
DiRT 4
Time-attack structure has no adaptive opponent
Tetris: Axis
no opponent modeling in main mode
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DiRT 4
Procedurally generated stages prevent full route memorisation
Tetris: Axis
random piece sequence drives play
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
Tetris: Axis
stacking strategy and clear 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.
