head to head
Shadow Tactics: Blades of the Shogun asks more than Hitman: Codename 47, and the gap is execution.

Optimization · Pure Optimization
The original stealth assassination sim where each mission is a clockwork puzzle.

Optimization · Practiced Mastery
Precisely timing simultaneous character actions to execute optimal stealth routes through fixed guard patterns.
Hitman: Codename 47 leans Optimization (Pure Optimization); Shadow Tactics: Blades of the Shogun leans Optimization (Practiced Mastery).
Shadow Tactics: Blades of the Shogun leans clearly harder on execution.
Hitman: Codename 47
Stiff aiming and unforgiving stealth movement
Shadow Tactics: Blades of the Shogun
Precise timing windows on simultaneous multi-character abilities matter
Shadow Tactics: Blades of the Shogun leans a little harder on reads, though the gap is small.
Hitman: Codename 47
Guards follow fixed scripted patrols
Shadow Tactics: Blades of the Shogun
Guard patrol routes are fixed; no opponent models you
Shadow Tactics: Blades of the Shogun leans a little harder on variance, though the gap is small.
Hitman: Codename 47
First-run guard routes and triggers are unknown
Shadow Tactics: Blades of the Shogun
Guard cone randomness is minimal once patterns are learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Hitman: Codename 47
Learning the level clockwork is the whole game
Shadow Tactics: Blades of the Shogun
Route planning and ability combo sequencing reduce to near-perfect solutions
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.
