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 time-travel puzzle game built entirely on deducing cross-era item interactions with no randomness.

Optimization · Pure Optimization
A chaotic comedy adventure whose elaborate multi-step puzzles test patience with absurd causal chains.
Day of the Tentacle leans Optimization (Pure Optimization); Deponia 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.
Day of the Tentacle
SCUMM interface eliminates any timing or motor demand
Deponia
Point-and-click with no timing elements
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Day of the Tentacle
No opponent; multi-era puzzles are fully scripted
Deponia
Comedy adventure with scripted characters throughout
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Day of the Tentacle
Deterministic world state across three time periods
Deponia
Deterministic puzzle world with fixed solutions
Day of the Tentacle leans a little harder on optimization, though the gap is small.
Day of the Tentacle
Cross-era cause-and-effect chains form a tightly solvable logic puzzle
Deponia
Convoluted Rube Goldberg puzzle chains demand careful causal 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.
