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.

Optimization · Pure Optimization
A comedic point-and-click adventure of pirate puzzles with fixed solutions.

Optimization · Pure Optimization
A tactile toy-box puzzler testing playful experimentation with hidden mechanisms.
Escape from Monkey Island leans Optimization (Pure Optimization); Gnog leans Optimization (Pure Optimization).
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
Gnog
Poking and spinning toy heads requires no dexterity
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
Gnog
The toys are charming clockwork, not minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Escape from Monkey Island
Puzzle solutions hidden until discovered
Gnog
Each head's mechanisms are unknown until fiddled with
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
Gnog
Discovering each contraption's interaction sequence is the 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.
