Hitman: Codename 47
Stiff aiming and unforgiving stealth movement
Rome: Total War
Real-time battle micro rewards quick unit handling
Rome: Total War leans clearly harder on reads.
Hitman: Codename 47
Guards follow fixed scripted patrols
Rome: Total War
Optional multiplayer battles; campaign AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hitman: Codename 47
First-run guard routes and triggers are unknown
Rome: Total War
Diplomacy and AI moves add modest fog
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
