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 · Pure Optimization
A crafting life-sim about running a workshop in a post-apocalyptic town.

Optimization · Pure Optimization
Open-world detective work testing evidence deduction without hand-holding.
My Time at Portia leans Optimization (Pure Optimization); The Sinking City leans Optimization (Pure Optimization).
My Time at Portia leans a little harder on execution, though the gap is small.
My Time at Portia
Light combat and crafting timing.
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.
My Time at Portia
NPCs follow scripts.
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.
My Time at Portia
Loot and gifts vary.
The Sinking City
Case clues are hidden information until investigated
My Time at Portia leans a little harder on optimization, though the gap is small.
My Time at Portia
Workshop scheduling and commissions reward optimization.
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.
