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

Optimization · Pure Optimization
A transgressive stealth horror game about an asylum escapee executing hunters from the shadows.

Optimization · Pure Optimization
A 2D sandbox where preparation and gear tiering carry boss fights.
Manhunt 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.
Manhunt 2
Execution-hold timing and stealth movement need steady hands
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.
Manhunt 2
Hunter AI patrols on fixed search scripts
Terraria
Bosses use scripted attacks; no adaptation.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Manhunt 2
Unknown patrol layouts until a level is scouted
Terraria
World seeds and loot drops randomized.
Terraria leans a little harder on optimization, though the gap is small.
Manhunt 2
Shadow routes and lure setups make levels solvable puzzles
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.
