head to head
Air-Sea Battle asks more than Sleeping Dogs, and the gap is reads.

Execution · Pure Mechanics
A 1977 timing test - lead the moving target and outscore the other gun.

Execution · Practiced Mastery
An open-world crime game where combat combos and driving skill carry the action.
Air-Sea Battle leans Execution (Pure Mechanics); Sleeping Dogs leans Execution (Practiced Mastery).
Air-Sea Battle leans a little harder on execution, though the gap is small.
Air-Sea Battle
Timing shots on moving targets is the entire game
Sleeping Dogs
brawling and driving need timing/aim
Air-Sea Battle leans clearly harder on reads.
Air-Sea Battle
Head-to-head play adds slight outguessing of the other gunner
Sleeping Dogs
scripted enemy AI, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Air-Sea Battle
Target patterns cycle predictably
Sleeping Dogs
minor loot and traffic randomness
Sleeping Dogs leans a little harder on optimization, though the gap is small.
Air-Sea Battle
Learning target speeds and angles is shallow but real
Sleeping Dogs
upgrade paths and mission routes solvable
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.
