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.

A real-time strategy game where mastering build orders and economy management decides most matches.

Optimization · Pure Optimization
An MMORPG dominated by theorycraft, gear math, and rotation execution.
Age of Empires II: HD Edition leans Optimization (Pure Optimization); World of Warcraft leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

World of Warcraft
Gear, talents, and rotation are mathematically solved
