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
The archetypal idle game where optimal purchase order is the entire skill.

Optimization · Pure Optimization
A noir puzzle journey through the Land of the Dead solved by untangling the game's own surreal logic.
Cookie Clicker leans Optimization (Pure Optimization); Grim Fandango leans Optimization (Pure Optimization).
Grim Fandango leans a little harder on execution, though the gap is small.
Cookie Clicker
Clicking is optional past the early game
Grim Fandango
Tank controls are awkward but never a skill test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cookie Clicker
No opponent
Grim Fandango
All characters follow scripted arcs; nothing adapts to the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cookie Clicker
Golden cookie timing randomness
Grim Fandango
A few timed sequences add minor uncertainty but nothing critical
Cookie Clicker leans a little harder on optimization, though the gap is small.
Cookie Clicker
Purchase order and ascension math are the game
Grim Fandango
Surreal multi-act puzzle chains demand patient causal reasoning
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.
