head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
An open-world crime game where combat combos and driving skill carry the action.

Execution · Practiced Mastery
Arcade brawler positioning and stamina against memorisable enemy waves.
Sleeping Dogs leans Execution (Practiced Mastery); Teenage Mutant Ninja Turtles II: The Arcade Game leans Execution (Practiced Mastery).
Teenage Mutant Ninja Turtles II: The Arcade Game leans a little harder on execution, though the gap is small.
Sleeping Dogs
brawling and driving need timing/aim
Teenage Mutant Ninja Turtles II: The Arcade Game
Crowd control timing and positioning under constant pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sleeping Dogs
scripted enemy AI, no adaptation
Teenage Mutant Ninja Turtles II: The Arcade Game
Foot Clan waves are quarter-munching scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sleeping Dogs
minor loot and traffic randomness
Teenage Mutant Ninja Turtles II: The Arcade Game
Spawns are fixed and memorisable
Teenage Mutant Ninja Turtles II: The Arcade Game leans a little harder on optimization, though the gap is small.
Sleeping Dogs
upgrade paths and mission routes solvable
Teenage Mutant Ninja Turtles II: The Arcade Game
Learning safe spots and boss patterns is the progression
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.
