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
Accessible car control amid demolition chaos rather than precision racing.

Execution · Pure Mechanics
An arcade-style soccer simulation with licensed national teams.
Dirt Showdown leans Execution (Practiced Mastery); World Tour Soccer 2002 leans Execution (Pure Mechanics).
World Tour Soccer 2002 leans a little harder on execution, though the gap is small.
Dirt Showdown
Drifting, boosting and ramming need solid car control
World Tour Soccer 2002
player control, passing and shooting precision
World Tour Soccer 2002 leans a little harder on reads, though the gap is small.
Dirt Showdown
Demolition modes reward predicting human movement a little
World Tour Soccer 2002
opponent play in human matches adds reads
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt Showdown
Crash physics and pack chaos add randomness
World Tour Soccer 2002
minor bounce/ref randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt Showdown
Event types and boost routes are quickly learnable
World Tour Soccer 2002
tactics and formation choices solvable
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.
