head to head
Five Nights at Freddy's 4 asks more than Don't Starve, and the gap is execution.

Variance · Systems & Chaos
Surviving randomised wilderness seasons by reading the world's systems and planning resources ahead.

Variance · Systems & Chaos
Listening for randomised audio cues and executing a defensive checking routine.
Don't Starve leans Variance (Systems & Chaos); Five Nights at Freddy's 4 leans Variance (Systems & Chaos).
Five Nights at Freddy's 4 leans clearly harder on execution.
Don't Starve
Kiting combat is simple but timing matters marginally
Five Nights at Freddy's 4
Reacting to breath audio cues within tight windows matters
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Don't Starve
Enemies follow fixed aggression rules, not player adaptation
Five Nights at Freddy's 4
Animatronic movement is RNG, not an adapting mind
Don't Starve leans a little harder on variance, though the gap is small.
Don't Starve
World generation, season timing, and loot rolls are highly random
Five Nights at Freddy's 4
Random animatronic positions stay hidden behind audio cues
Don't Starve leans a little harder on optimization, though the gap is small.
Don't Starve
Seasonal resource planning and character synergies are deeply 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.
