DOOM (2016)
Aim, movement, glory-kill timing all peak.
DOOM (2016) leans a little harder on reads, though the gap is small.
Alpha Runner
no opponent, solo runner experience
DOOM (2016)
Demons scripted attack patterns.
Alpha Runner leans a little harder on variance, though the gap is small.
Alpha Runner

DOOM (2016) leans clearly harder on optimization.
Alpha Runner
route memorization for high scores
DOOM (2016)
Rune and weapon mod picks meaningful.
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.
