head to head
Dragon Spirit: The New Legend asks more than Half-Life 2, and the gap is execution.

Execution · Pure Mechanics
A vertical shoot-'em-up testing dodging and aim across scripted waves.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Dragon Spirit: The New Legend leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
Dragon Spirit: The New Legend leans clearly harder on execution.
Dragon Spirit: The New Legend
Dodging bullets and aiming is the lead skill
Half-Life 2
Gravity gun and shooting demand precision.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Spirit: The New Legend
Enemies follow fixed patterns, not adaptive
Half-Life 2
Combine AI scripted, non-adaptive.
Dragon Spirit: The New Legend leans clearly harder on variance.
Dragon Spirit: The New Legend
Some enemy spawn timing varies
Half-Life 2
Almost no randomness.
Dragon Spirit: The New Legend leans a little harder on optimization, though the gap is small.
Dragon Spirit: The New Legend
Power-up routing and pattern memorization help survival
Half-Life 2
Linear progression with no builds.
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.
