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 · Systems & Chaos
Uncovering hidden item-puzzle solutions along a fixed time-travel story path.

Optimization · Pure Optimization
Open-world detective work testing evidence deduction without hand-holding.
The Silent Age leans Optimization (Systems & Chaos); The Sinking City leans Optimization (Pure Optimization).
The Sinking City leans a little harder on execution, though the gap is small.
The Silent Age
Pointing and clicking carries no physical test
The Sinking City
Clunky combat is deliberately undemanding
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Silent Age
A fixed story; nothing adapts
The Sinking City
Monsters and citizens follow fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Silent Age
Puzzle solutions are hidden information until discovered
The Sinking City
Case clues are hidden information until investigated
The Sinking City leans a little harder on optimization, though the gap is small.
The Silent Age
Item-combination logic converges to a single known path
The Sinking City
Cross-referencing evidence and city archives is the deduction core
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.
