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 comedic point-and-click adventure of pirate puzzles with fixed solutions.

Optimization · Systems & Chaos
Uncovering hidden item-puzzle solutions along a fixed time-travel story path.
Escape from Monkey Island leans Optimization (Pure Optimization); The Silent Age 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.
Escape from Monkey Island
Pointing and walking only
The Silent Age
Pointing and clicking carries no physical test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Escape from Monkey Island
No opponent
The Silent Age
A fixed story; nothing adapts
The Silent Age leans a little harder on variance, though the gap is small.
Escape from Monkey Island
Puzzle solutions hidden until discovered
The Silent Age
Puzzle solutions are hidden information until discovered
Escape from Monkey Island leans a little harder on optimization, though the gap is small.
Escape from Monkey Island
Once known, every puzzle has one fixed answer
The Silent Age
Item-combination logic converges to a single known path
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.
