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 · Practiced Mastery
Vehicular mayhem testing car handling plus knowing when wrecking beats racing.

Execution · Practiced Mastery
Car control under pursuit pressure plus memorising city routes mission by mission.
Carmageddon II: Carpocalypse Now leans Execution (Practiced Mastery); Driver 2: Back on the Streets 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.
Carmageddon II: Carpocalypse Now
Perfect car control trivialises wrecking AI opponents and surviving
Driver 2: Back on the Streets
Wrestling the car physics through chase missions is the test
Carmageddon II: Carpocalypse Now leans a little harder on reads, though the gap is small.
Carmageddon II: Carpocalypse Now
AI drivers follow set behaviours, never modelling the player
Driver 2: Back on the Streets
Police AI follows fixed pursuit logic, not adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Carmageddon II: Carpocalypse Now
Pickup spawns and physics chaos add modest run-to-run noise
Driver 2: Back on the Streets
Traffic placement adds run-to-run noise in chases
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Carmageddon II: Carpocalypse Now
Choosing wreck-versus-race strategy and upgrade economy is solvable
Driver 2: Back on the Streets
Learning city layouts and mission routes carries completion
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.
