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

Optimization · Pure Optimization
Cyberpunk point-and-click adventure through a dystopian Australian mega-city.

Optimization · Systems & Chaos
A ghost-noir adventure testing clue association and patient investigation.
Beneath a Steel Sky leans Optimization (Pure Optimization); The Blackwell Convergence 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.
Beneath a Steel Sky
Point-and-click; no dexterity required
The Blackwell Convergence
Pointing and clicking has no dexterity test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Beneath a Steel Sky
No opponent; scripted characters
The Blackwell Convergence
Characters are scripted dialogue trees
The Blackwell Convergence leans a little harder on variance, though the gap is small.
Beneath a Steel Sky
First-run puzzle surprises only
The Blackwell Convergence
The mystery's facts are hidden until uncovered
Beneath a Steel Sky leans a little harder on optimization, though the gap is small.
Beneath a Steel Sky
Inventory puzzle chains are fully solvable
The Blackwell Convergence
Connecting clues and notebook entries is the core puzzle
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.
