head to head
Neither is simply harder - they are hard in different places. Baldur's Gate 3 demands more optimization; Five Nights at Freddy's 4 demands more execution.

Optimization · Systems & Chaos
A D&D CRPG where build optimization and dice variance dominate every encounter.

Variance · Systems & Chaos
Listening for randomised audio cues and executing a defensive checking routine.
Baldur's Gate 3 leans Optimization (Systems & Chaos); Five Nights at Freddy's 4 leans Variance (Systems & Chaos).
Five Nights at Freddy's 4 leans clearly harder on execution.
Baldur's Gate 3
Turn-based; no input dexterity.
Five Nights at Freddy's 4
Reacting to breath audio cues within tight windows matters
Baldur's Gate 3 leans clearly harder on reads.
Baldur's Gate 3
Companions/enemies scripted, not adaptive to player modeling.
Five Nights at Freddy's 4
Animatronic movement is RNG, not an adapting mind
Baldur's Gate 3 leans a little harder on variance, though the gap is small.
Baldur's Gate 3
Dice rolls, hidden checks, encounter RNG everywhere.
Five Nights at Freddy's 4
Random animatronic positions stay hidden behind audio cues
Baldur's Gate 3 leans clearly harder on optimization.
Baldur's Gate 3
Builds, party comp, action economy fully solvable.
Five Nights at Freddy's 4
Door-checking routines become a learnable optimal loop
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.
