head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
Procedural space exploration sandbox with crafting depth.

Optimization · Pure Optimization
Planning stealth kill sequences around shuffled NPC routines.
No Man's Sky leans Optimization (Pure Optimization); Party Hard 2 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.
No Man's Sky
Light shooter and flight inputs
Party Hard 2
Timing kills matters, but pace is deliberate
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
No Man's Sky
Mostly solo, sparse PvP
Party Hard 2
Partygoer AI is randomized patterns, not adaptive minds
Party Hard 2 leans a little harder on variance, though the gap is small.
No Man's Sky
Procedural planets and loot
Party Hard 2
Level item spawns and NPC routes shuffle per attempt
No Man's Sky leans a little harder on optimization, though the gap is small.
No Man's Sky
Base, freighter, expedition progression
Party Hard 2
Sequencing kills, traps and escapes is the actual 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.
