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
A rail shooter testing reflex execution against fully memorisable enemy waves.

Execution · Practiced Mastery
Memorising punishing side-scroller layouts and executing them without mistakes.
Star Fox leans Execution (Practiced Mastery); The Terminator 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.
Star Fox
Dodging, shooting and barrel rolls on rails demand reflexes
The Terminator
Stiff jumps and enemy gauntlets demand precise platform timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox
Every enemy wave is a fixed scripted pattern
The Terminator
Enemies are fully scripted patterns with no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox
Routes and spawns are deterministic per path
The Terminator
Nearly everything is fixed once levels are memorised
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox
Memorising wave patterns and route choices for score
The Terminator
Memorising layouts and ammo spots is most of the progress
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.
