head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Pure Mechanics
Old-school platforming execution through short, fixed western levels.

Execution · Practiced Mastery
Momentum-driven execution over fixed levels rewarding memorised routes.
Gunman Clive leans Execution (Pure Mechanics); Sonic the Hedgehog 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.
Gunman Clive
Tight jumps and duck-shoot timing carry all sixteen levels
Sonic the Hedgehog 3
Holding speed through fixed hazards demands sharp reactions
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gunman Clive
Bandits and bosses run fixed patterns
Sonic the Hedgehog 3
Badniks and bosses repeat identical scripts
Sonic the Hedgehog 3 leans a little harder on variance, though the gap is small.
Gunman Clive
Levels never change between attempts
Sonic the Hedgehog 3
Levels never change between runs
Sonic the Hedgehog 3 leans a little harder on optimization, though the gap is small.
Gunman Clive
Boss pattern learning and weapon upgrades round out clears
Sonic the Hedgehog 3
Route choice and emerald collection reward memorised play
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.
