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
Side-on turn-based tactics where you manually aim ricocheting bullets for a steambot pirate crew.

Optimization · Pure Optimization
A Viking survival game where preparing properly trivialises each biome boss.
SteamWorld Heist leans Optimization (Pure Optimization); Valheim leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
SteamWorld Heist
Manual aim and ricochet shots reward steady hands
Valheim
Block-and-parry timing matters in boss fights.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
SteamWorld Heist
Enemy bots follow fixed behaviors
Valheim
Enemies follow scripted AI; no adaptation.
SteamWorld Heist leans a little harder on variance, though the gap is small.
SteamWorld Heist
Procedural ship layouts and loot drops
Valheim
World seed and biome layout introduce mild randomness.
Valheim leans a little harder on optimization, though the gap is small.
SteamWorld Heist
Crew builds, weapon picks, and turn routing carry runs
Valheim
Gear progression and base infrastructure define progress.
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.
