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
A basic arcade soccer game testing input timing and simple positioning.

Execution · Practiced Mastery
Accessible car control amid demolition chaos rather than precision racing.
Champions World Class Soccer leans Execution (Practiced Mastery); Dirt Showdown 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.
Champions World Class Soccer
Passing, shooting and tackling timing carry every play
Dirt Showdown
Drifting, boosting and ramming need solid car control
Champions World Class Soccer leans a little harder on reads, though the gap is small.
Champions World Class Soccer
Two-player mode lets you predict a human opponent
Dirt Showdown
Demolition modes reward predicting human movement a little
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Champions World Class Soccer
Little randomness once team ratings are known
Dirt Showdown
Crash physics and pack chaos add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Champions World Class Soccer
Formation choice and team selection give a known edge
Dirt Showdown
Event types and boost routes are quickly learnable
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.
