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

Execution · Practiced Mastery
A psychological action-horror story about a writer fighting darkness with a flashlight.

Optimization · Practiced Mastery
San Francisco hacker sandbox blending stealth, drones, and toy gadgets.
Alan Wake leans Execution (Practiced Mastery); Watch Dogs 2 leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Alan Wake
Flashlight-then-shoot timing and dodges
Watch Dogs 2
Shooting and driving moderate input demands.
Watch Dogs 2 leans a little harder on reads, though the gap is small.
Alan Wake
Taken spawn on triggers, never adapt
Watch Dogs 2
Enemy AI scripted; some PvP invasions exist.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alan Wake
Ambush placements surprise once
Watch Dogs 2
Hack outcomes and patrols vary mildly.
Watch Dogs 2 leans a little harder on optimization, though the gap is small.
Alan Wake
Resource management and set encounters learnable
Watch Dogs 2
Gadgets, hacks, mission approaches 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.
