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

Optimization · Pure Optimization
The 1986 original that founded the Japanese RPG template.

Optimization · Pure Optimization
A fixed-solution puzzle adventure where finding the right inventory combination unlocks every obstacle.
Dragon Quest leans Optimization (Pure Optimization); The Secret of Monkey Island leans Optimization (Pure Optimization).
The Secret of Monkey Island leans a little harder on execution, though the gap is small.
Dragon Quest
Menu commands only
The Secret of Monkey Island
Clicking inventory items demands no twitch skill whatsoever
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Quest
No adaptive opposition
The Secret of Monkey Island
No adaptive opponent; all puzzles are fixed and authored
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Quest
Battle RNG and unknown world first time
The Secret of Monkey Island
Some hidden items require exploration but solutions are invariant
The Secret of Monkey Island leans a little harder on optimization, though the gap is small.
Dragon Quest
Grind thresholds and routes are fully solvable
The Secret of Monkey Island
Correct item combinations and dialogue chains fully determine progress
