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
A short graphics showcase testing basic shooter execution for twenty minutes.

Execution · Pure Mechanics
A casual carnival pointing test with light high-score target memory.
Half-Life 2: Lost Coast leans Execution (Practiced Mastery); Toy Story Mania! leans Execution (Pure Mechanics).
Toy Story Mania! leans a little harder on execution, though the gap is small.
Half-Life 2: Lost Coast
A short stretch of standard Half-Life 2 gunplay
Toy Story Mania!
Rapid target pointing and firing is the whole test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2: Lost Coast
A handful of scripted Combine soldiers
Toy Story Mania!
Galleries are scripted carnival sequences
Toy Story Mania! leans a little harder on variance, though the gap is small.
Half-Life 2: Lost Coast
One fixed level with nothing hidden
Toy Story Mania!
Bonus target spawns vary slightly between plays
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2: Lost Coast
Too brief to develop any systems layer
Toy Story Mania!
Learning high-value target locations adds thin strategy
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.
