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.

Variance · Systems & Chaos
Surviving randomised wilderness seasons by reading the world's systems and planning resources ahead.

Optimization · Systems & Chaos
A beloved story-driven Mystery Dungeon RPG where you play as a Pokémon exploring randomized dungeons.
Don't Starve leans Variance (Systems & Chaos); Pokémon Mystery Dungeon: Explorers of Sky leans Optimization (Systems & Chaos).
Don't Starve leans a little harder on execution, though the gap is small.
Don't Starve
Kiting combat is simple but timing matters marginally
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.
Don't Starve
Enemies follow fixed aggression rules, not player adaptation
Pokémon Mystery Dungeon: Explorers of Sky
No adaptive opponent
Don't Starve leans a little harder on variance, though the gap is small.
Don't Starve
World generation, season timing, and loot rolls are highly random
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.
Don't Starve
Seasonal resource planning and character synergies are deeply solvable
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.
