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 · Practiced Mastery
Underwater dogfighting testing piloting and aim through scripted missions.

Execution · Pure Mechanics
The 70s-cinema getaway driving game with famously demanding physics.
AquaNox leans Execution (Practiced Mastery); Driver leans Execution (Pure Mechanics).
Driver leans a little harder on execution, though the gap is small.
AquaNox
Six-degree underwater dogfighting demands piloting and aim
Driver
Handbrake control and pursuit driving by feel
AquaNox leans a little harder on reads, though the gap is small.
AquaNox
Mission enemies attack on fixed scripts
Driver
Police AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
AquaNox
Missions play out identically each attempt
Driver
Traffic adds mild unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
AquaNox
Ship loadout and weapon choice add modest planning
Driver
City routes and mission tactics 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.
