Axis by axis
Execution3 vs 3
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Planet Coaster
Precise track and scenery placement rewards manual dexterity
Planet Zoo
Animal habitat and path construction demands deliberate precision
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 Coaster
No adaptive opponent; guests follow scripted happiness rules
Planet Zoo
Animals and guests follow scripted need systems
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Planet Coaster
Guest mood noise is low and quickly mappable
Planet Zoo
Animal welfare stats have minor stochastic variation
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 Coaster
Queue routing, pricing, and ride placement are the solvable core
Planet Zoo
Species welfare requirements and financial management are fully solvable
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.
