Broken Sword: The Sleeping Dragon
light action segments, mostly puzzle-paced
Professor Layton and the Diabolical Box
Stylus taps - zero dexterity demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Broken Sword: The Sleeping Dragon
no adaptive antagonist present
Professor Layton and the Diabolical Box
No opponent; a parade of standalone brainteasers
Professor Layton and the Diabolical Box leans a little harder on variance, though the gap is small.
Broken Sword: The Sleeping Dragon
deterministic puzzle outcomes
Professor Layton and the Diabolical Box
Puzzles are fixed; only their first encounter surprises
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Broken Sword: The Sleeping Dragon
item and dialogue logic puzzles
Professor Layton and the Diabolical Box
Each brainteaser has one clean logical solution to find
