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

Optimization · Practiced Mastery
An MMO where grinding out solvable gear-enhancement systems dominates over its action combat.

Optimization · Pure Optimization
Maintaining senate favor and province chains while executing real-time cohort tactics.
Black Desert leans Optimization (Practiced Mastery); Total War: Rome II leans Optimization (Pure Optimization).
Black Desert leans a little harder on execution, though the gap is small.
Black Desert
combo-based combat needs real precision
Total War: Rome II
Cohort line management and flanking cavalry demand real-time micro
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Black Desert
PvP siege battles reward reading opponents
Total War: Rome II
AI generals follow scripted behaviors without adapting to the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Black Desert
gear enhancement is heavily randomized
Total War: Rome II
Random political events and dynastic loyalty shifts add campaign variance
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Black Desert
grinding routes and builds are solvable
Total War: Rome II
Senate favor management and province chains form a solvable campaign system
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.
