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

Optimization · Pure Optimization
Puzzle sequel where glove powers paint blocks to solve physical room logic.
Deponia leans Optimization (Pure Optimization); Q.U.B.E. 2 leans Optimization (Pure Optimization).
Q.U.B.E. 2 leans a little harder on execution, though the gap is small.
Deponia
Point-and-click with no timing elements
Q.U.B.E. 2
Occasional timing on moving blocks only
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
Q.U.B.E. 2
No adaptive element exists
Deponia leans a little harder on variance, though the gap is small.
Deponia
Deterministic puzzle world with fixed solutions
Q.U.B.E. 2
Deterministic puzzles with full information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Deponia
Convoluted Rube Goldberg puzzle chains demand careful causal mapping
Q.U.B.E. 2
Glove-power combinations resolve to clean solutions
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.
