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 expanded sequel sending the SMERSH operative on more elaborate WWII infiltration missions.

Optimization · Pure Optimization
Procedural space exploration sandbox with crafting depth.
Death to Spies: Moment of Truth leans Optimization (Pure Optimization); No Man's Sky leans Optimization (Pure Optimization).
Death to Spies: Moment of Truth leans a little harder on execution, though the gap is small.
Death to Spies: Moment of Truth
Stealth inputs are forgiving once the plan exists
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.
Death to Spies: Moment of Truth
Guards never learn from your previous attempts
No Man's Sky
Mostly solo, sparse PvP
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Death to Spies: Moment of Truth
Initial uncertainty about patrols and objective placement
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.
Death to Spies: Moment of Truth
Perfect routes through clockwork levels are fully solvable
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.
