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 gleefully violent 1997 Build-engine shooter starring undead gunslinger Caleb.

Execution · Pure Mechanics
A test of fast, precise shooting and map navigation against scripted but relentless enemies.
Blood leans Execution (Practiced Mastery); Doom (1993) leans Execution (Pure Mechanics).
Doom (1993) leans a little harder on execution, though the gap is small.
Blood
Fast Build-engine combat demands aim and dodging
Doom (1993)
Precise movement and shooting against relentless enemy pressure
Blood leans a little harder on reads, though the gap is small.
Blood
Niche multiplayer only; campaign enemies are scripted
Doom (1993)
Enemies follow scripted patrol and attack patterns, not adaptive
Doom (1993) leans a little harder on variance, though the gap is small.
Blood
Some enemy spawn and hitscan unpredictability
Doom (1993)
Enemy placement is fixed but unknown on first run through levels
Blood leans a little harder on optimization, though the gap is small.
Blood
Secret hunting, weapon economy, route knowledge
Doom (1993)
Level routing and resource management determine survival efficiency
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.
