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
Managing a survivor community's economy and defenses after the collapse.
No Man's Sky leans Optimization (Pure Optimization); Survivalist 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
Survivalist
Top-down combat needs only modest aim and kiting
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
Survivalist
NPC factions follow systemic scripts, not adaptation
Survivalist leans a little harder on variance, though the gap is small.
No Man's Sky
Procedural planets and loot
Survivalist
Scavenging finds and event triggers are hidden until explored
No Man's Sky leans a little harder on optimization, though the gap is small.
No Man's Sky
Base, freighter, expedition progression
Survivalist
Community building, farming and trade economy are the solvable core
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.
