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 chaotic comedy adventure whose elaborate multi-step puzzles test patience with absurd causal chains.

Optimization · Pure Optimization
A puzzle-forward adventure testing creative lateral thinking against a fixed authored solution space.
Deponia leans Optimization (Pure Optimization); Return to Monkey Island 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.
Deponia
Point-and-click with no timing elements
Return to Monkey Island
Modern hint system and relaxed interface remove all reflex demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deponia
Comedy adventure with scripted characters throughout
Return to Monkey Island
Entirely authored puzzles with no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Deponia
Deterministic puzzle world with fixed solutions
Return to Monkey Island
Virtually no randomness; solutions are static
Deponia leans a little harder on optimization, though the gap is small.
Deponia
Convoluted Rube Goldberg puzzle chains demand careful causal mapping
Return to Monkey Island
Lateral-thinking item puzzles require mapping cause and effect chains
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.
