head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Practiced Mastery
A 3D platformer where DK smashes through fully destructible terrain hunting buried treasures.

Optimization · Practiced Mastery
A mining metroidvania about digging efficient tunnels, hauling ore, and compounding upgrades.
Donkey Kong Bananza leans Optimization (Practiced Mastery); SteamWorld Dig 2 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.
Donkey Kong Bananza
Punch-heavy traversal and boss fights
SteamWorld Dig 2
Light platforming and digging dexterity
SteamWorld Dig 2 leans a little harder on reads, though the gap is small.
Donkey Kong Bananza
Enemies follow scripted behaviour
SteamWorld Dig 2
Scripted enemies only
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong Bananza
Buried secrets unknown until dug up
SteamWorld Dig 2
Procedural ore pockets add mild run-to-run unknowns
SteamWorld Dig 2 leans a little harder on optimization, though the gap is small.
Donkey Kong Bananza
Destructible terrain rewards creative routing and collectible hunting
SteamWorld Dig 2
Dig routing, resource economy, and upgrade ordering 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.
