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

Optimization · Practiced Mastery
A linear horror chase game tested by nerve management and environmental navigation under scripted creature pressure.

Optimization · Systems & Chaos
Puzzle adventure about coaxing a giant half-tame creature through ancient ruins.
Still Wakes the Deep leans Optimization (Practiced Mastery); The Last Guardian leans Optimization (Systems & Chaos).
Still Wakes the Deep leans a little harder on execution, though the gap is small.
Still Wakes the Deep
Narrow corridor sprints and climbing sections under creature pressure
The Last Guardian
Slow climbing and platforming, very forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Still Wakes the Deep
No adaptive opponent; creature follows scripted trigger events
The Last Guardian
Trico is willful but not modeling you adversarially
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Still Wakes the Deep
Creature patrol windows and some object locations are unknown first run
The Last Guardian
Trico's unpredictable compliance adds noise
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Still Wakes the Deep
Safe-path knowledge and object-use sequences are memorisable
The Last Guardian
Environmental puzzles with intended solutions
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.
