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
Global flight sim built on real weather and procedures.

Execution · Practiced Mastery
Looking Glass's 1996 squad-command sim of powered-armor combat on alien battlefields.
Microsoft Flight Simulator (2020) leans Execution (Practiced Mastery); Terra Nova: Strike Force Centauri 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
Terra Nova: Strike Force Centauri
Piloting powered armor and aiming under fire is demanding
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Microsoft Flight Simulator (2020)
No adaptive opponents, ATC scripted
Terra Nova: Strike Force Centauri
Enemy forces follow mission scripts, never adapt
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
Terra Nova: Strike Force Centauri
Unknown enemy placements on first mission attempts
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
Terra Nova: Strike Force Centauri
Squad orders, loadouts and approach routes are plannable
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.
