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.

Optimization · Pure Optimization
A classic arcade game about computing the trajectory to land in a bucket.

Optimization · Practiced Mastery
Community resource management under randomised zombie pressure, with light action execution.
Human Cannonball leans Optimization (Pure Optimization); State of Decay leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Human Cannonball
Firing requires no real motor precision
State of Decay
Melee and driving are functional, not demanding
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Human Cannonball
No opponent to model in this arcade game
State of Decay
Zombies swarm by simple rules, never adapting
State of Decay leans a little harder on variance, though the gap is small.
Human Cannonball
Some variations randomize the target distance
State of Decay
Dynamic events, infestations and survivor traits roll randomly
Human Cannonball leans a little harder on optimization, though the gap is small.
Human Cannonball
Calculating angle, speed and position is the whole puzzle
State of Decay
Base building, resource runs and survivor management are the game
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.
