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 gritty WWII Call of Duty that introduced the Zombies mode.

Execution · Pure Mechanics
A comedic twitch top-down shooter set in a cartoon war.
Call of Duty: World at War leans Execution (Practiced Mastery); Super Trench Attack! 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.
Call of Duty: World at War
Twitch gunfights in fast multiplayer lobbies
Super Trench Attack!
Twitch aiming and dodging is the core
Call of Duty: World at War leans a little harder on reads, though the gap is small.
Call of Duty: World at War
Human opponents reward positioning prediction
Super Trench Attack!
Enemies follow scripted AI, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: World at War
Random lobbies, spawns, and zombie waves
Super Trench Attack!
Enemy spawns add modest unpredictability
Call of Duty: World at War leans a little harder on optimization, though the gap is small.
Call of Duty: World at War
Perk loadouts and map control are learnable
Super Trench Attack!
Weapon and upgrade choices offer light planning
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.
