Prey (2017)
Wrench and Gloo timing modest.
Reads0 vs 1

Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Portal
Pure puzzle-solving optimization.
Prey (2017)
Neuromods, builds, station routing deeply 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.
