head to head
Call of Duty: Modern Warfare 2 asks more than WWF: Super Wrestlemania, and the gap is execution.

Execution · Competitive PvP
Blockbuster 2009 sequel famous for killstreak chains and frantic multiplayer.

Execution · Competitive PvP
An arcade wrestling game testing grapple timing and reading opponent moves.
Call of Duty: Modern Warfare 2 leans Execution (Competitive PvP); WWF: Super Wrestlemania leans Execution (Competitive PvP).
Call of Duty: Modern Warfare 2 leans clearly harder on execution.
Call of Duty: Modern Warfare 2
Fast time-to-kill rewards raw aim and reflex
WWF: Super Wrestlemania
Grapple and move timing drive matches
Call of Duty: Modern Warfare 2 leans clearly harder on reads.
Call of Duty: Modern Warfare 2
Outguessing human rotations and flanks
WWF: Super Wrestlemania
Human opponents allow reading grapple attempts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Call of Duty: Modern Warfare 2
Spawn flips and killstreak randomness
WWF: Super Wrestlemania
Some randomness in move success
Call of Duty: Modern Warfare 2 leans clearly harder on optimization.
Call of Duty: Modern Warfare 2
Killstreak economy, loadout and map knowledge
WWF: Super Wrestlemania
Move knowledge and stamina give modest edge
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.
