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
Family-friendly dungeon crawler that swaps Minecraft's building for loot and hack-and-slash.

Optimization · Practiced Mastery
Community resource management under randomised zombie pressure, with light action execution.
Minecraft Dungeons 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.
Minecraft Dungeons
Dodge-rolls and kiting through mob swarms
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.
Minecraft Dungeons
Enemies are scripted hordes
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.
Minecraft Dungeons
Random loot and enchantment rolls drive power
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.
Minecraft Dungeons
Gear synergies and enchant builds carry difficulty
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.
