head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Turn-based tactical fights ruled by scarce-ammo economy and positioning.

Optimization · Pure Optimization
Methodically dissecting intricate puzzle boxes whose mechanisms are fully solvable.
Gorky 17 leans Optimization (Pure Optimization); The Room Three 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.
Gorky 17
Turn-based menu inputs only
The Room Three
Rotating and prodding mechanisms takes no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gorky 17
Monsters follow deterministic AI routines
The Room Three
The Craftsman is narrative dressing, not an adaptive mind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gorky 17
Hit rolls and unknown encounters add tension
The Room Three
Hidden mechanisms are unknown until inspected, then fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gorky 17
Strict ammo economy and positioning puzzles are the whole fight
The Room Three
Each puzzle box is a fully solvable mechanical system
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.
