head to head
Call of Duty: Modern Warfare 2 asks more than Yu Yu Hakusho: Ghost Files - Dark Tournament, and the gap is execution.

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

Execution · Competitive PvP
An anime fighting game testing execution and prediction against human opponents.
Call of Duty: Modern Warfare 2 leans Execution (Competitive PvP); Yu Yu Hakusho: Ghost Files - Dark Tournament leans Execution (Competitive PvP).

Call of Duty: Modern Warfare 2
Outguessing human rotations and flanks
Yu Yu Hakusho: Ghost Files - Dark Tournament

Yu Yu Hakusho: Ghost Files - Dark Tournament
Some card-mode RNG and matchup chaos
Call of Duty: Modern Warfare 2 leans a little harder on optimization, though the gap is small.
Call of Duty: Modern Warfare 2
Killstreak economy, loadout and map knowledge
Yu Yu Hakusho: Ghost Files - Dark Tournament
Character movesets and matchups reward study
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.
