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.

Variance · Systems & Chaos
Managing dice-roll risk across randomly generated maps with careful party planning.

Optimization · Systems & Chaos
A beloved story-driven Mystery Dungeon RPG where you play as a Pokémon exploring randomized dungeons.
For the King leans Variance (Systems & Chaos); Pokémon Mystery Dungeon: Explorers of Sky leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
For the King
Turn-based slot rolls need no dexterity
Pokémon Mystery Dungeon: Explorers of Sky
Turn-based; no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
For the King
Enemies follow simple deterministic combat AI
Pokémon Mystery Dungeon: Explorers of Sky
No adaptive opponent
For the King leans a little harder on variance, though the gap is small.
For the King
Dice-roll combat and random maps dominate single runs
Pokémon Mystery Dungeon: Explorers of Sky
Random floors and item luck, cushioned by forgiving design
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
For the King
Focus economy, routing and loadout play beat the odds
Pokémon Mystery Dungeon: Explorers of Sky
Type matchups, recruiting, and move sets are solvable
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.
