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 continuation puzzle journey where mechanical and environmental obstacles yield to patient reasoning.
Deponia leans Optimization (Pure Optimization); Syberia 2 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
Syberia 2
Interface unchanged; no motor skill tested
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
Syberia 2
Continuation of scripted narrative with fixed characters
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
Syberia 2
Deterministic world state throughout
Deponia leans a little harder on optimization, though the gap is small.
Deponia
Convoluted Rube Goldberg puzzle chains demand careful causal mapping
Syberia 2
Environmental and mechanical puzzles reward patient logical mapping
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.
