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

Execution · Practiced Mastery
A family-tuned brawler-platformer testing modest timing and simple puzzle solutions.

Execution · Practiced Mastery
Gentle collect-and-glide platforming with light routing depth.
Knack II leans Execution (Practiced Mastery); Spyro the Dragon leans Execution (Practiced Mastery).
Spyro the Dragon leans a little harder on execution, though the gap is small.
Knack II
Light combo timing and platforming pitched at families
Spyro the Dragon
Gliding and charging need modest precision at most
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Knack II
Enemies run simple scripts without adaptation
Spyro the Dragon
Gnorcs repeat one behaviour forever
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Knack II
Levels are fixed with nothing hidden beyond first sight
Spyro the Dragon
Gem locations are fixed once levels are explored
Spyro the Dragon leans a little harder on optimization, though the gap is small.
Knack II
Size-swap puzzles have single obvious solutions
Spyro the Dragon
Collection routing and glide lines reward light planning
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.
