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 · Light / Casual
A deliberately trivial chase advergame testing only basic steering.

Execution · Practiced Mastery
A short graphics showcase testing basic shooter execution for twenty minutes.
Dash of Destruction leans Execution (Light / Casual); Half-Life 2: Lost Coast leans Execution (Practiced Mastery).
Half-Life 2: Lost Coast leans a little harder on execution, though the gap is small.
Dash of Destruction
Simple steering is the only demand, deliberately easy
Half-Life 2: Lost Coast
A short stretch of standard Half-Life 2 gunplay
Dash of Destruction leans a little harder on reads, though the gap is small.
Dash of Destruction
Chase AI barely reacts; local human play adds a sliver
Half-Life 2: Lost Coast
A handful of scripted Combine soldiers
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dash of Destruction
City layouts are fixed and tiny
Half-Life 2: Lost Coast
One fixed level with nothing hidden
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dash of Destruction
Routes are learned in minutes by design
Half-Life 2: Lost Coast
Too brief to develop any systems layer
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.
