head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Execution · Pure Mechanics
A test of fast, precise shooting and map navigation against scripted but relentless enemies.

Execution · Practiced Mastery
A sword-and-gun action shooter rewarding combo timing mastery and careful upgrade investment against scripted demon hordes.
Doom (1993) leans Execution (Pure Mechanics); Shadow Warrior (2013) 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.
Doom (1993)
Precise movement and shooting against relentless enemy pressure
Shadow Warrior (2013)
Sword combos and gunplay require precise timing and input chaining
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Enemies follow scripted patrol and attack patterns, not adaptive
Shadow Warrior (2013)
All enemies are scripted demons with fixed attack patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Doom (1993)
Enemy placement is fixed but unknown on first run through levels
Shadow Warrior (2013)
Upgrade drop randomness introduces mild run-to-run variance
Shadow Warrior (2013) leans a little harder on optimization, though the gap is small.
Doom (1993)
Level routing and resource management determine survival efficiency
Shadow Warrior (2013)
Ki power and upgrade tree investment form a meaningful build 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.
