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
A primitive dungeon crawl testing stat management against random rolls.

Optimization · Pure Optimization
Open-world detective work testing evidence deduction without hand-holding.
Akalabeth: World of Doom 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.
Akalabeth: World of Doom
Turn-based keypresses carry no physical demand
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.
Akalabeth: World of Doom
Monsters follow primitive fixed behaviour
The Sinking City
Monsters and citizens follow fixed scripts
Akalabeth: World of Doom leans a little harder on variance, though the gap is small.
Akalabeth: World of Doom
Dungeon generation and stat rolls inject early-CRPG randomness
The Sinking City
Case clues are hidden information until investigated
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Akalabeth: World of Doom
Stat management and grinding efficiency decide survival
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.
