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 non-Euclidean exploration puzzle testing your willingness to abandon assumptions about space.

Optimization · Pure Optimization
Board-game distillation of Hitman into elegant fully-solvable turn puzzles.
Antichamber leans Optimization (Pure Optimization); Hitman Go leans Optimization (Pure Optimization).
Antichamber leans a little harder on execution, though the gap is small.
Antichamber
Navigation has no twitch demands
Hitman Go
Turn-based taps, zero dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Antichamber
No opponent; solo non-Euclidean exploration
Hitman Go
Enemy pieces move on fixed deterministic rules
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Antichamber
World is deterministic once its rules are understood
Hitman Go
All information visible on the board
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Antichamber
Deducing the non-Euclidean spatial logic and gun mechanics governing each room
Hitman Go
Each diorama is a literally solvable movement puzzle
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.
