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
Dark remix of classic Hitman missions built on the same clockwork puzzle stealth.

Optimization · Pure Optimization
Procedural space exploration sandbox with crafting depth.
Hitman: Contracts leans Optimization (Pure Optimization); No Man's Sky leans Optimization (Pure Optimization).
Hitman: Contracts leans a little harder on execution, though the gap is small.
Hitman: Contracts
Precise positioning and timed takedowns
No Man's Sky
Light shooter and flight inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hitman: Contracts
Scripted patrols and fixed reactions only
No Man's Sky
Mostly solo, sparse PvP
No Man's Sky leans a little harder on variance, though the gap is small.
Hitman: Contracts
Unknown layouts and triggers on first attempts
No Man's Sky
Procedural planets and loot
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Hitman: Contracts
Route, disguise, and timing solve each mission
No Man's Sky
Base, freighter, expedition progression
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.
