head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
A dungeon-crawler spin-off testing build management across randomised otherworlds.

Optimization · Practiced Mastery
Community resource management under randomised zombie pressure, with light action execution.
Silent Hill: Book of Memories leans Optimization (Practiced Mastery); 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.
Silent Hill: Book of Memories
Twin-stick melee and dodge timing matter moderately
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.
Silent Hill: Book of Memories
Monsters follow simple scripted aggression
State of Decay
Zombies swarm by simple rules, never adapting
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Hill: Book of Memories
Procedural dungeon layouts and loot rolls vary each run
State of Decay
Dynamic events, infestations and survivor traits roll randomly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Silent Hill: Book of Memories
Karma builds, weapon upkeep and puzzle rooms reward system mastery
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.
