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 · Practiced Mastery
The 3DS Mario Kart that added gliders, underwater driving, and kart customisation.

Execution · Practiced Mastery
A frantic co-op cooking game where execution speed, partner reads, and optimal kitchen routing determine your score.
Mario Kart 7 leans Execution (Practiced Mastery); Overcooked 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart 7
Drift boosts, gliding, and underwater control
Overcooked 2
High-speed chopping, plating, and movement under pressure is the ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mario Kart 7
Online lobbies reward anticipating rivals' items
Overcooked 2
Anticipating co-op partner actions requires real-time social reads
Mario Kart 7 leans a little harder on variance, though the gap is small.
Mario Kart 7
Item luck shapes every race
Overcooked 2
Level hazards and order queues introduce random variation
Overcooked 2 leans a little harder on optimization, though the gap is small.
Mario Kart 7
Kart customisation and track-specific routes
Overcooked 2
Optimal kitchen routing and task assignment is learnable per level
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.
