Planet ZoovsPortal
Planet Zoo asks more than Portal, and the gap is variance.
Planet Zoo
Optimization · Pure Optimization
Designing animal habitats that satisfy complex welfare systems while maintaining zoo profitability.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Planet Zoo leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Planet ZooPortal
Axis by axis
Execution3 vs 4
Portal leans a little harder on execution, though the gap is small.
Planet Zoo
Animal habitat and path construction demands deliberate precision
Portal
Portal placement timing modest.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Planet Zoo
Animals and guests follow scripted need systems
Portal
No adversary modeling player.
Variance2 vs 0
Planet Zoo leans clearly harder on variance.
Planet Zoo
Animal welfare stats have minor stochastic variation
Portal
Deterministic chambers; no randomness.
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Planet Zoo
Species welfare requirements and financial management are fully solvable
Portal
Pure puzzle-solving optimization.
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.
