Broken AI barely follows its own scripts
Grand Theft Auto IV
Scripted AI, no adaptive opponent modeling.
Variance1 vs 2
Grand Theft Auto IV leans a little harder on variance, though the gap is small.

Encounters are fixed and trivially learnable
Grand Theft Auto IV
Minor mission variance.
Optimization3 vs 3

Aliens: Colonial Marines
Loadout choices barely matter against weak opposition
Grand Theft Auto IV
Mission routing and weapon picks learnable.
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.
