head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
Global flight sim built on real weather and procedures.

Execution · Practiced Mastery
Tests deliberate aim and squad-level planning against scripted insurgent encounters.
Microsoft Flight Simulator (2020) leans Execution (Practiced Mastery); Operation Flashpoint: Red River leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Microsoft Flight Simulator (2020)
Procedure execution, instrument flying skill
Operation Flashpoint: Red River
Authentic ballistics punish sloppy aim and positioning
Operation Flashpoint: Red River leans a little harder on reads, though the gap is small.
Microsoft Flight Simulator (2020)
No adaptive opponents, ATC scripted
Operation Flashpoint: Red River
Insurgent AI is scripted spawns, not an adapting mind
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Microsoft Flight Simulator (2020)
Real weather and live traffic
Operation Flashpoint: Red River
Enemy placements are unknown until contact
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Microsoft Flight Simulator (2020)
Flight planning, systems mastery, routing
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.
