Axis by axis
Execution3 vs 4
Terraria leans a little harder on execution, though the gap is small.
Core Keeper
Boss fights and melee require learned dodge timing
Terraria
Boss fights require dodging and aim under pressure.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Core Keeper
All bosses and enemies are scripted with fixed patterns
Terraria
Bosses use scripted attacks; no adaptation.
Variance5 vs 3
Core Keeper leans clearly harder on variance.
Core Keeper
World seed, ore placement, and loot drops are randomised
Terraria
World seeds and loot drops randomized.
Optimization7 vs 8
Terraria leans a little harder on optimization, though the gap is small.
Core Keeper
Mining routes, crafting progression, and boss order are systematic
Terraria
Gear progression and arena prep solve every boss.
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.
