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
Plannable stealth routing punctuated by precise ballistic marksmanship.

Optimization · Practiced Mastery
Open-world survival-flavored tactical shooter built around gear progression and base infiltration.
Sniper Elite III leans Execution (Practiced Mastery); Tom Clancy's Ghost Recon Breakpoint leans Optimization (Practiced Mastery).
Sniper Elite III leans a little harder on execution, though the gap is small.
Sniper Elite III
Ballistic long shots demand steady, compensated aim
Tom Clancy's Ghost Recon Breakpoint
Stealth shooting and drone play reward precise aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sniper Elite III
Enemy AI follows mappable alert and search routines
Tom Clancy's Ghost Recon Breakpoint
Drones and soldiers run fixed behaviors, never model you
Tom Clancy's Ghost Recon Breakpoint leans a little harder on variance, though the gap is small.
Sniper Elite III
Patrol details and wind vary slightly per attempt
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.
Sniper Elite III
Open maps reward planned routes, sound masking and relocation
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.
