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 · Pure Mechanics
Arcade car control across loose surfaces, weather and door-to-door packs.

Execution · Practiced Mastery
A mobile soccer simulation game.
Dirt 5 leans Execution (Pure Mechanics); Real Soccer 2009 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 5
Sliding off-road cars on mixed surfaces is the whole test
Real Soccer 2009
passing and shooting precision are core skills
Real Soccer 2009 leans a little harder on reads, though the gap is small.
Dirt 5
Pack racing adds light wheel-to-wheel jockeying
Real Soccer 2009
AI defense has limited adaptive counterplay
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt 5
Dynamic weather shifts grip unpredictably
Real Soccer 2009
minor randomness in ball physics/outcomes
Real Soccer 2009 leans a little harder on optimization, though the gap is small.
Dirt 5
Car class knowledge and line choice reward study
Real Soccer 2009
formation and tactics are 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.
