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 · Practiced Mastery
Zelda-meets-God-of-War action adventure starring the horseman War.

Execution · Practiced Mastery
A campy 16-bit run-and-gun about rescuing neighbors from B-movie monsters.
Darksiders leans Execution (Practiced Mastery); Zombies Ate My Neighbors 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.
Darksiders
combo-driven combat with dodge timing
Zombies Ate My Neighbors
Dodging monsters while sniping with squirt guns
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Darksiders
enemies are scripted
Zombies Ate My Neighbors
Monster movie AI is fully patterned
Zombies Ate My Neighbors leans a little harder on variance, though the gap is small.
Darksiders
world and bosses are fixed
Zombies Ate My Neighbors
Victim placement varies slightly per level
Darksiders leans a little harder on optimization, though the gap is small.
Darksiders
Zelda-style dungeons and upgrade routing
Zombies Ate My Neighbors
Weapon-versus-monster matchups and level routing
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.
