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
A rally sim whose procedural stages keep variance alive while rewarding clean car control.

Execution · Practiced Mastery
Rapid capsule placement against a clock, with planning for chains under random pill draws.
DiRT 4 leans Execution (Pure Mechanics); Dr. Mario leans Execution (Practiced Mastery).
DiRT 4 leans a little harder on execution, though the gap is small.
DiRT 4
Procedural stages still demand consistent throttle and apex discipline
Dr. Mario
Fast capsule placement under rising speed decides clears
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
Dr. Mario
Versus mode exists but garbage exchange rewards speed, not prediction
DiRT 4 leans a little harder on variance, though the gap is small.
DiRT 4
Procedurally generated stages prevent full route memorisation
Dr. Mario
Random pill colors against fixed virus layouts, quickly bounded
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
Dr. Mario
Chain setups and virus-clearing order follow known patterns
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.
