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

Execution · Practiced Mastery
A toy-soldier shooter testing basic aim through fixed plastic battlefields.

Execution · Practiced Mastery
A retro-Soviet action shooter mixing gunplay with light upgrade strategy.
Army Men: Sarge's Heroes leans Execution (Practiced Mastery); Atomic Heart 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.
Army Men: Sarge's Heroes
Clunky third-person aiming carries the campaign
Atomic Heart
Shooting and dodging carry the combat.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Army Men: Sarge's Heroes
Split-screen versus adds a sliver of human prediction
Atomic Heart
Robot enemies follow scripted patterns.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Army Men: Sarge's Heroes
Levels are fixed with little hidden
Atomic Heart
Encounters largely fixed.
Atomic Heart leans a little harder on optimization, though the gap is small.
Army Men: Sarge's Heroes
Weapon pickups and routes barely need planning
Atomic Heart
Upgrades and weapon crafting learnable.
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.
