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
Strategic dismemberment under resource pressure, solved by upgrade planning and practiced limb-aiming.

Execution · Practiced Mastery
Fast pattern-matching of cookie rows under accelerating speed pressure.
Dead Space (2008) leans Execution (Practiced Mastery); Yoshi's Cookie leans Execution (Practiced Mastery).
Dead Space (2008) leans a little harder on execution, though the gap is small.
Dead Space (2008)
Precise limb-targeting under Necromorph pressure is the core skill
Yoshi's Cookie
Sliding rows quickly under rising speed pressures the hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space (2008)
Necromorphs follow fixed approach patterns, not player modelling
Yoshi's Cookie
Versus mode adds only light opponent awareness
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dead Space (2008)
Store stock is deterministic; minor drop variance on kills
Yoshi's Cookie
Cookie spawns randomise but patterns are bounded
Dead Space (2008) leans a little harder on optimization, though the gap is small.
Dead Space (2008)
Weapon upgrading, power-node routing and stasis timing are optimisable
Yoshi's Cookie
Recognising clear setups efficiently is half the score
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.
