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 streamlined click-along action RPG famous for its seamless world.

Optimization · Pure Optimization
Open-world detective work testing evidence deduction without hand-holding.
Dungeon Siege leans Optimization (Pure Optimization); The Sinking City leans Optimization (Pure Optimization).
The Sinking City leans a little harder on execution, though the gap is small.
Dungeon Siege
Combat mostly resolves itself
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.
Dungeon Siege
Mobs charge on simple scripts
The Sinking City
Monsters and citizens follow fixed scripts
The Sinking City leans a little harder on variance, though the gap is small.
Dungeon Siege
Loot drops vary modestly
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.
Dungeon Siege
Party builds and pack-mule logistics are the game
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.
