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
Soft-body physics sandbox driving and crashing.

Execution · Practiced Mastery
An endless-runner shooter testing steering and aim against zombie crowds.
BeamNG.drive leans Execution (Practiced Mastery); Into the Dead 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.
BeamNG.drive
Soft-body physics car control
Into the Dead 2
Steering and aiming while auto-running drives survival
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
BeamNG.drive
Mostly sandbox, no adaptive opponents
Into the Dead 2
Zombies shamble on scripts, no prediction
Into the Dead 2 leans a little harder on variance, though the gap is small.
BeamNG.drive
Emergent crash physics outcomes
Into the Dead 2
Spawn placement and pickup drops vary each run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
BeamNG.drive
Vehicle tuning, scenario routing
Into the Dead 2
Weapon loadout and upgrade choices reward planning
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.
