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
A chaotic vehicular-combat racer where destructive driving skill leads.

Execution · Pure Mechanics
Holding clean lines at speed through traffic on memorisable point-to-point roads.
Carmageddon TDR 2000 leans Execution (Practiced Mastery); The Need for Speed leans Execution (Pure Mechanics).
The Need for Speed leans a little harder on execution, though the gap is small.
Carmageddon TDR 2000
vehicular combat driving and crash control
The Need for Speed
Holding racing lines at speed through traffic is the test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Carmageddon TDR 2000
AI drivers barely adapt to player
The Need for Speed
AI rivals and police follow fixed behaviour
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Carmageddon TDR 2000
crash physics and pedestrian randomness
The Need for Speed
Traffic patterns add mild run-to-run noise
Carmageddon TDR 2000 leans a little harder on optimization, though the gap is small.
Carmageddon TDR 2000
vehicle upgrade and route optimization
The Need for Speed
Track knowledge and car choice settle quickly
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.
