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

Execution · Practiced Mastery
A gritty crime shooter following two doomed mercenaries through botched heists.

Execution · Pure Mechanics
A cute endless runner starring a dog dodging traffic.
Kane & Lynch: Dead Men leans Execution (Practiced Mastery); Puppy Cross leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Kane & Lynch: Dead Men
Cover shooting accuracy under pressure
Puppy Cross
Simple lane-dodging reflex timing
Kane & Lynch: Dead Men leans a little harder on reads, though the gap is small.
Kane & Lynch: Dead Men
Fragile Alliance betrayals add faint human guessing
Puppy Cross
No opponents present
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kane & Lynch: Dead Men
Set-piece encounters vary little
Puppy Cross
Obstacle spawn randomness varies runs
Kane & Lynch: Dead Men leans a little harder on optimization, though the gap is small.
Kane & Lynch: Dead Men
Squad orders and encounter knowledge
Puppy Cross
Minimal systems, casual endless runner
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.
