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

Execution · Practiced Mastery
A top-down co-op shooter testing aim and upgrade optimization against alien swarms.

Execution · Practiced Mastery
Loot-driven co-op heist shooter where builds and route knowledge make perfect crimes.
From Space leans Execution (Practiced Mastery); Payday 2 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.
From Space
Twin-stick aiming and dodging swarms is core
Payday 2
Sustained gunfights and stealth execution under pressure
From Space leans a little harder on reads, though the gap is small.
From Space
Aliens are scripted/random, not adaptive minds
Payday 2
Cops and guards follow spawn scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
From Space
Random spawns and drops add chaos
Payday 2
Random vault locations, guard patrols, and escrow rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
From Space
Weapon upgrades and squad coordination reward planning
Payday 2
Skill builds and stealth route planning per heist
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.
