head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
A noir puzzle journey through the Land of the Dead solved by untangling the game's own surreal logic.

Optimization · Pure Optimization
A Myst-successor puzzle adventure about decoding alien machinery across spliced worlds.
Grim Fandango leans Optimization (Pure Optimization); Obduction 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.
Grim Fandango
Tank controls are awkward but never a skill test
Obduction
Walking and clicking only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grim Fandango
All characters follow scripted arcs; nothing adapts to the player
Obduction
No opponents at all
Grim Fandango leans a little harder on variance, though the gap is small.
Grim Fandango
A few timed sequences add minor uncertainty but nothing critical
Obduction
Deterministic alien machinery
Grim Fandango leans a little harder on optimization, though the gap is small.
Grim Fandango
Surreal multi-act puzzle chains demand patient causal reasoning
Obduction
Number-system and swap-machine puzzles are fully solvable
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.
