head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Accessible car control amid demolition chaos rather than precision racing.

Execution · Practiced Mastery
Frozen-planet shooter about managing heat while gunning down giant bugs.
Dirt Showdown leans Execution (Practiced Mastery); Lost Planet: Extreme Condition 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.
Dirt Showdown
Drifting, boosting and ramming need solid car control
Lost Planet: Extreme Condition
Grapple movement and Akrid weak-point shooting
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt Showdown
Demolition modes reward predicting human movement a little
Lost Planet: Extreme Condition
Multiplayer modes add some mind games
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
Lost Planet: Extreme Condition
Campaign encounters are fixed
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
Lost Planet: Extreme Condition
Thermal energy management and boss weak points
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.
