Cocoon leans Optimization (Pure Optimization); PC Building Simulator 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.
Cocoon
Inputs are simple movement and a button.
PC Building Simulator
Careful part assembly is procedural, not twitchy.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cocoon
Puzzles are fixed designs.
PC Building Simulator

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cocoon
No randomness.
PC Building Simulator
Job orders vary slightly day to day.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cocoon
Pure puzzle logic, solvable by reasoning.
PC Building Simulator
Diagnosing builds and budgeting parts for jobs is the whole game.
