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.

Variance · Systems & Chaos
The harder sequel that swaps doors for a mask and forces a frantic multitasking routine against more animatronics.

Variance · Systems & Chaos
Co-op looting under randomised monster threats, testing careful handling and risk management.
Five Nights at Freddy's 2 leans Variance (Systems & Chaos); R.E.P.O. leans Variance (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Five Nights at Freddy's 2
Mask, flashlight, and music box juggling demands fast hands
R.E.P.O.
Physics-based carrying of fragile loot punishes clumsy hands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Five Nights at Freddy's 2
RNG-driven animatronics, not adaptive opponents
R.E.P.O.
Monsters follow randomised scripts, not adaptive minds
R.E.P.O. leans a little harder on variance, though the gap is small.
Five Nights at Freddy's 2
More stalkers, more hidden movement rolls
R.E.P.O.
Map layouts, loot and monster spawns are hidden each run
Five Nights at Freddy's 2 leans a little harder on optimization, though the gap is small.
Five Nights at Freddy's 2
Optimal check rotations make late nights solvable
R.E.P.O.
Route planning and extraction economy converge with experience
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.
