head to head
Total War: Attila asks more than Warcraft: Orcs & Humans, and the gap is variance.

Optimization · Pure Optimization
Balancing horde economy against collapsing empire pressure while executing real-time siege tactics.

Optimization · Practiced Mastery
The original 1994 RTS pitting orc and human bases against each other in Azeroth.
Total War: Attila leans Optimization (Pure Optimization); Warcraft: Orcs & Humans leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Total War: Attila
Fire deployment and cavalry routing demand real-time tactical decisions
Warcraft: Orcs & Humans
Clunky unit micro and click speed still matter
Warcraft: Orcs & Humans leans a little harder on reads, though the gap is small.
Total War: Attila
AI factions follow scripted migration paths; human play adds reads
Warcraft: Orcs & Humans
Human multiplayer adds genuine build mind games
Total War: Attila leans clearly harder on variance.
Total War: Attila
Hunnic migration pressure and disease outbreaks add meaningful campaign unknowns
Warcraft: Orcs & Humans
Fog of war hides enemy composition
Total War: Attila leans a little harder on optimization, though the gap is small.
Total War: Attila
Settlement razing decisions and horde economy optimization form the core
Warcraft: Orcs & Humans
Build orders and economy timing dominate
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.
