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

The classic survival horror sequel where ammo budgeting and route knowledge tame Raccoon City.

Optimization · Pure Optimization
A 2D sandbox where preparation and gear tiering carry boss fights.
Resident Evil 2 leans Optimization (Pure Optimization); Terraria 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.
Resident Evil 2
Tank controls and aim need competence, not mastery
Terraria
Boss fights require dodging and aim under pressure.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Resident Evil 2
Zombies are scripted, never adaptive
Terraria
Bosses use scripted attacks; no adaptation.
Resident Evil 2 leans a little harder on variance, though the gap is small.
Resident Evil 2
First-run item and enemy placement is hidden information
Terraria
World seeds and loot drops randomized.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Resident Evil 2
Routing, ammo economy, and puzzles fully converge on replay
Terraria
Gear progression and arena prep solve every boss.
