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.

Optimization · Practiced Mastery
A WWII stealth game about ghosting through guard patrols as a British spy.

Optimization · Practiced Mastery
An open-world action game where hacking the city's infrastructure is your main weapon.
Velvet Assassin leans Optimization (Practiced Mastery); Watch Dogs leans Optimization (Practiced Mastery).
Watch Dogs leans a little harder on execution, though the gap is small.
Velvet Assassin
Stealth kill timing and shadow movement
Watch Dogs
Cover shooting and driving at modest difficulty
Watch Dogs leans a little harder on reads, though the gap is small.
Velvet Assassin
Guards patrol on fixed scripts
Watch Dogs
Online invasions add a small human element
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Velvet Assassin
Patrol layouts unknown only on first attempt
Watch Dogs
Guard placements are knowable on approach
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Velvet Assassin
Routes through guard patterns are the solvable core
Watch Dogs
Hacking chains and camera routes make stealth solvable
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.
