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

Optimization · Pure Optimization
Day-job hybrid of relaxed spearfishing dives and nightly sushi-bar management.
Abiotic Factor leans Optimization (Systems & Chaos); Dave the Diver 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.
Abiotic Factor
Combat in tight facility corridors requires precise aim and positioning
Dave the Diver
harpoon aiming and sushi-service minigames
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
Dave the Diver
no adaptive opponent
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
Dave the Diver
daily fish spawns and sea changes vary
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
Dave the Diver
restaurant economy and gear upgrades drive progress
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.
