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
Procedural space exploration sandbox with crafting depth.

Optimization · Pure Optimization
The classic survival horror sequel where ammo budgeting and route knowledge tame Raccoon City.
No Man's Sky leans Optimization (Pure Optimization); Resident Evil 2 leans Optimization (Pure Optimization).
Resident Evil 2 leans a little harder on execution, though the gap is small.
No Man's Sky
Light shooter and flight inputs
Resident Evil 2
Tank controls and aim need competence, not mastery
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
Resident Evil 2
Zombies are scripted, never adaptive
Resident Evil 2 leans a little harder on variance, though the gap is small.
No Man's Sky
Procedural planets and loot
Resident Evil 2
First-run item and enemy placement is hidden information
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
No Man's Sky
Base, freighter, expedition progression
Resident Evil 2
Routing, ammo economy, and puzzles fully converge on replay
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.
