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

Optimization · Pure Optimization
Fantasy RTS spin-off of Rise of Nations with three wildly asymmetric civilizations and hero units.

Optimization · Practiced Mastery
The original 1994 RTS pitting orc and human bases against each other in Azeroth.
Rise of Nations: Rise of Legends 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.
Rise of Nations: Rise of Legends
Real-time economy and army juggling needs speed
Warcraft: Orcs & Humans
Clunky unit micro and click speed still matter
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Rise of Nations: Rise of Legends
PvP rewards countering opponents' hero and tech commitments
Warcraft: Orcs & Humans
Human multiplayer adds genuine build mind games
Warcraft: Orcs & Humans leans a little harder on variance, though the gap is small.
Rise of Nations: Rise of Legends
Map layouts and neutral sites vary
Warcraft: Orcs & Humans
Fog of war hides enemy composition
Rise of Nations: Rise of Legends leans a little harder on optimization, though the gap is small.
Rise of Nations: Rise of Legends
Asymmetric faction trees and expansion timing reward deep study
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.
