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 · Pure Mechanics
WWII gunfight execution with light multiplayer prediction.

Execution · Pure Mechanics
A physics-based wrestling brawler about controlling ragdoll combat against opponents.
Call of Duty 3 leans Execution (Pure Mechanics); Drunken Wrestlers 2 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 3
Aimbot trivialises both campaign and multiplayer gunfights
Drunken Wrestlers 2
physics-based ragdoll control precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty 3
Multiplayer adds modest human positional prediction
Drunken Wrestlers 2
predicting human opponent's wrestling moves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty 3
Scripted setpieces and spawn flow add minor unknowns
Drunken Wrestlers 2
physics ragdoll randomness affects outcomes
Call of Duty 3 leans a little harder on optimization, though the gap is small.
Call of Duty 3
Map knowledge and weapon choice reward light study
Drunken Wrestlers 2
minimal, mostly reflexive physical play
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.
