head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Guiding fragile squads with precise targeting and memorised mission routes.

Execution · Practiced Mastery
Global flight sim built on real weather and procedures.
Cannon Fodder 2 leans Execution (Practiced Mastery); Microsoft Flight Simulator (2020) 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.
Cannon Fodder 2
Precise mouse targeting under fire keeps fragile troops alive
Microsoft Flight Simulator (2020)
Procedure execution, instrument flying skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cannon Fodder 2
Enemy soldiers spawn and charge on scripts
Microsoft Flight Simulator (2020)
No adaptive opponents, ATC scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cannon Fodder 2
Hazard placements are unknown until a costly first attempt
Microsoft Flight Simulator (2020)
Real weather and live traffic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cannon Fodder 2
Route order and grenade economy per mission are learnable
Microsoft Flight Simulator (2020)
Flight planning, systems mastery, routing
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.
