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

Execution · Pure Mechanics
Precision 3D platformer of narrow corridors, crates, and unforgiving jumps.

Execution · Pure Mechanics
Tests execution against dense scripted boss patterns in handheld run-and-gun form.
Crash Bandicoot leans Execution (Pure Mechanics); Gunstar Super Heroes leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Tight jumps on narrow paths punish slop
Gunstar Super Heroes
Dense run-and-gun action demands precise dodging and weapon control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Hazards are fixed patterns
Gunstar Super Heroes
Boss patterns are elaborate but completely scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Everything scripted and placed
Gunstar Super Heroes
Stages play out identically each run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Box routes and gem requirements are learnable
Gunstar Super Heroes
Learning screen-filling boss movesets is the core progression
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.
