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

Execution · Pure Mechanics
Push-forward arena FPS where movement and aim are the whole game.

Execution · Pure Mechanics
A cover-based run-and-gun testing precise shooting and pattern memorization.
DOOM (2016) leans Execution (Pure Mechanics); Rolling Thunder 2 leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Aim, movement, glory-kill timing all peak.
Rolling Thunder 2
Precise shooting, cover-jumping and timing carry every stage
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Demons scripted attack patterns.
Rolling Thunder 2
Solo/co-op - enemies follow scripted spawn patterns
Rolling Thunder 2 leans a little harder on variance, though the gap is small.
DOOM (2016)
Minimal encounter randomness.
Rolling Thunder 2
Enemy appearances are fixed once memorized
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DOOM (2016)
Rune and weapon mod picks meaningful.
Rolling Thunder 2
Learning spawn points and weapon management is the meta-game
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.
