Grand Theft Auto V leans a little harder on reads, though the gap is small.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.

Operation Flashpoint: Red River leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Operation Flashpoint: Red River

Grand Theft Auto V
Heists, money loops, builds learnable.
Operation Flashpoint: Red River
Loadouts, class roles and approach planning decide engagements
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.
