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

Optimization · Pure Optimization
Using stealth-phase positioning to construct optimal ambushes against scripted patrols.

Optimization · Pure Optimization
A space tower-defense game solved by optimal module placement under timed pressure.
Mutant Year Zero: Road to Eden leans Optimization (Pure Optimization); Space Run: Fast and Safe Delivery 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.
Mutant Year Zero: Road to Eden
Stealth positioning before combat demands spatial precision
Space Run: Fast and Safe Delivery
Real-time placement under pressure adds mild twitch
Space Run: Fast and Safe Delivery leans a little harder on reads, though the gap is small.
Mutant Year Zero: Road to Eden
Enemies patrol fixed routes; no adaptive opponent modeling
Space Run: Fast and Safe Delivery
Enemy waves are scripted, not adapting to you
Mutant Year Zero: Road to Eden leans a little harder on variance, though the gap is small.
Mutant Year Zero: Road to Eden
Hit chances and mutation procs introduce meaningful RNG
Space Run: Fast and Safe Delivery
Wave compositions and timing add bounded surprises
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Mutant Year Zero: Road to Eden
Stalker trait loadouts and pre-combat positioning are tight optimization puzzles
Space Run: Fast and Safe Delivery
Optimal weapon placement and resource use win runs
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.
