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
Capcom's polished CPS2 vertical shooter built around a charging lock-on bomb and tight scoring play.

Execution · Practiced Mastery
Precise rally car control over stages that reward memorisation and tuning.
19XX: The War Against Destiny leans Execution (Practiced Mastery); Dirt 3 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.
19XX: The War Against Destiny
Capcom bullet density plus lock-on bomb timing
Dirt 3
Car control on loose surfaces is a high physical ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
19XX: The War Against Destiny
Boss patterns are fixed
Dirt 3
Racing the clock or scripted AI, nobody adapts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
19XX: The War Against Destiny
Little hidden once stages are studied
Dirt 3
Surface conditions and minor physics noise per run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
19XX: The War Against Destiny
Charge-shot usage and scoring routes reward deep study
Dirt 3
Stage knowledge and setup tuning reward study
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.
