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
A story-first adventure with gentle item-puzzle logic as its only test.

Optimization · Systems & Chaos
A point-and-click adventure where a stolen painting drags George and Nico into a Gnostic conspiracy.
Back to the Future: The Game leans Optimization (Pure Optimization); Broken Sword 5: The Serpent's Curse 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.

Click-driven; no manual skill ceiling.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Broken Sword 5: The Serpent's Curse

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.
