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 · Systems & Chaos
Surviving and optimising a research facility escape by solving its crafting systems against scripted anomalies.

Optimization · Pure Optimization
A 2D sandbox of procedurally generated planets driven by crafting progression.
Abiotic Factor leans Optimization (Systems & Chaos); Starbound leans Optimization (Pure Optimization).
Abiotic Factor leans a little harder on execution, though the gap is small.
Abiotic Factor
Combat in tight facility corridors requires precise aim and positioning
Starbound
Light platforming and combat, generous margins
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Abiotic Factor
Anomaly and creature AI is scripted with fixed patterns
Starbound
Procedural NPCs follow simple fixed behaviours
Abiotic Factor leans a little harder on variance, though the gap is small.
Abiotic Factor
Loot crates, anomaly behaviour, and facility section contents carry RNG
Starbound
Procedural planets and loot keep early exploration unknown
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Abiotic Factor
Facility routing, crafting tree unlocks, and power grid design are solvable
Starbound
Gear tiers, farming, and progression routes dominate
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.
