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
An ultraviolent co-op brawler dragging four fighters through a grim drug-soaked Soviet underworld.

Execution · Practiced Mastery
Arcade car control at speed over memorised tracks with scripted police pressure.
Mother Russia Bleeds leans Execution (Practiced Mastery); Need for Speed: Hot Pursuit 2 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.
Mother Russia Bleeds
Brutal crowd fights demand sharp dodges, grabs, and timing.
Need for Speed: Hot Pursuit 2
High-speed cornering and traffic dodging are the whole test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mother Russia Bleeds
Enemies are scripted, never modelling you.
Need for Speed: Hot Pursuit 2
AI racers and cops follow rubber-band scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mother Russia Bleeds
Minor enemy mix and syringe-drop randomness.
Need for Speed: Hot Pursuit 2
Cop spawns and traffic add mild run-to-run noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mother Russia Bleeds
Nekro drug management and wave layouts are learnable.
Need for Speed: Hot Pursuit 2
Track knowledge and racing lines are learnable and fixed
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.
