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
A gritty WWII Call of Duty that introduced the Zombies mode.

Execution · Practiced Mastery
A shared-world looter shooter mixing sharp FPS execution with an RNG loot treadmill and solvable raid puzzles.
Call of Duty: World at War leans Execution (Practiced Mastery); Destiny 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.
Call of Duty: World at War
Twitch gunfights in fast multiplayer lobbies
Destiny
FPS gunplay and raid mechanics demand real aim.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: World at War
Human opponents reward positioning prediction
Destiny
Crucible PvP adds genuine human prediction.
Destiny leans a little harder on variance, though the gap is small.
Call of Duty: World at War
Random lobbies, spawns, and zombie waves
Destiny
RNG loot drops famously gate progression.
Destiny leans a little harder on optimization, though the gap is small.
Call of Duty: World at War
Perk loadouts and map control are learnable
Destiny
Loadout meta and raid routes are solvable systems.
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.
