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 polished 3D platformer showcasing PlayStation's mascots.

Execution · Practiced Mastery
A short graphics showcase testing basic shooter execution for twenty minutes.
Astro Bot leans Execution (Practiced Mastery); Half-Life 2: Lost Coast leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Astro Bot
Polished but forgiving 3D platforming
Half-Life 2: Lost Coast
A short stretch of standard Half-Life 2 gunplay
Astro Bot leans a little harder on reads, though the gap is small.
Astro Bot
Scripted enemies
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.
Astro Bot
Static stages
Half-Life 2: Lost Coast
One fixed level with nothing hidden
Astro Bot leans a little harder on optimization, though the gap is small.
Astro Bot
Collectible and time-trial routing
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.
