head to head
Call of Duty: Modern Warfare 2 asks more than Art of Fighting 2, and the gap is variance.

Execution · Competitive PvP
Early fighting-game execution and spacing, plus mind-games against humans.

Execution · Competitive PvP
Blockbuster 2009 sequel famous for killstreak chains and frantic multiplayer.
Art of Fighting 2 leans Execution (Competitive PvP); Call of Duty: Modern Warfare 2 leans Execution (Competitive PvP).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Art of Fighting 2
Spirit-gauge specials and spacing demand drilled precision
Call of Duty: Modern Warfare 2
Fast time-to-kill rewards raw aim and reflex
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Art of Fighting 2
Human matches turn on baiting and conditioning
Call of Duty: Modern Warfare 2
Outguessing human rotations and flanks
Call of Duty: Modern Warfare 2 leans clearly harder on variance.
Art of Fighting 2
Nothing random in the fixed roster
Call of Duty: Modern Warfare 2
Spawn flips and killstreak randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Art of Fighting 2
Notoriously hard AI patterns are studyable scripts, not minds
Call of Duty: Modern Warfare 2
Killstreak economy, loadout and map knowledge
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.
