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

Variance · Systems & Chaos
Building a psyche and gaming dice checks through a dense authored narrative.

Optimization · Systems & Chaos
Deduction under permanent consequences - assembling hidden case facts into correct conclusions.
Disco Elysium: The Final Cut leans Variance (Systems & Chaos); Lacuna leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Disco Elysium: The Final Cut
Pure reading and clicking, no physical layer
Lacuna
Walking and dialogue choices need no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Disco Elysium: The Final Cut
Every character responds along authored branches
Lacuna
Suspects follow a fixed script regardless of you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Disco Elysium: The Final Cut
Dice checks and hidden thresholds gate outcomes
Lacuna
The case is hidden information; wrong reads stick permanently
Lacuna leans a little harder on optimization, though the gap is small.
Disco Elysium: The Final Cut
Skill builds and check preparation are the solvable layer
Lacuna
Cross-referencing clues into correct deductions is the test
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.
