Building comparison
head to head
Half-Life 2vsWarhammer 40,000: Space Marine
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.
Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Warhammer 40,000: Space Marine
Execution · Practiced Mastery
Third-person action where Captain Titus chainswords through ork hordes without a cover system.
Half-Life 2 leans Execution (Pure Mechanics); Warhammer 40,000: Space Marine leans Execution (Practiced Mastery).

Axis by axis
Execution6 vs 6
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Gravity gun and shooting demand precision.
Warhammer 40,000: Space Marine
Melee-shooting flow and execution timing carry combat
Reads1 vs 1
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Combine AI scripted, non-adaptive.
Warhammer 40,000: Space Marine
Ork hordes follow scripted aggression
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Almost no randomness.
Warhammer 40,000: Space Marine
Encounters are fixed and predictable
Optimization3 vs 4
Warhammer 40,000: Space Marine leans a little harder on optimization, though the gap is small.
Half-Life 2
Linear progression with no builds.
Warhammer 40,000: Space Marine
Weapon choice and fury management are simple to learn
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.
