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 · Pure Optimization
Cozy space exploration and base-building sandbox.

Optimization · Pure Optimization
A strategy game about damming a fluid enemy with an optimized energy economy.
Astroneer leans Optimization (Pure Optimization); Creeper World 4 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.
Astroneer
Light terrain tool inputs
Creeper World 4
Light real-time micro placing and moving units
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Astroneer
No adaptive opponents
Creeper World 4
The creep flows by fixed simulation rules
Astroneer leans a little harder on variance, though the gap is small.
Astroneer
Planet resource distribution
Creeper World 4
Fluid behaviour is deterministic once terrain is understood
Creeper World 4 leans a little harder on optimization, though the gap is small.
Astroneer
Base layout, power chains, automation
Creeper World 4
Energy economy and frontline routing decide everything
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.
