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

Execution · Practiced Mastery
Looking Glass's 1996 squad-command sim of powered-armor combat on alien battlefields.

Optimization · Practiced Mastery
Open-world survival-flavored tactical shooter built around gear progression and base infiltration.
Terra Nova: Strike Force Centauri leans Execution (Practiced Mastery); Tom Clancy's Ghost Recon Breakpoint leans Optimization (Practiced Mastery).
Terra Nova: Strike Force Centauri leans a little harder on execution, though the gap is small.
Terra Nova: Strike Force Centauri
Piloting powered armor and aiming under fire is demanding
Tom Clancy's Ghost Recon Breakpoint
Stealth shooting and drone play reward precise aim
Tom Clancy's Ghost Recon Breakpoint leans a little harder on reads, though the gap is small.
Terra Nova: Strike Force Centauri
Enemy forces follow mission scripts, never adapt
Tom Clancy's Ghost Recon Breakpoint
Drones and soldiers run fixed behaviors, never model you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Terra Nova: Strike Force Centauri
Unknown enemy placements on first mission attempts
Tom Clancy's Ghost Recon Breakpoint
Patrols and gear drops add light randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Terra Nova: Strike Force Centauri
Squad orders, loadouts and approach routes are plannable
Tom Clancy's Ghost Recon Breakpoint
Gear score, builds, and infiltration routes drive success
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.
