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.

Optimization · Pure Optimization
Optimizing city placement, social policies, and victory routing under randomized map unknowns.

Optimization · Pure Optimization
A broken-system RPG where influence manipulation and prestige class chaining produce dominant power spikes.
Civilization V leans Optimization (Pure Optimization); Knights of the Old Republic II: The Sith Lords 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.
Civilization V
UI actions need no precision; speed is not a factor
Knights of the Old Republic II: The Sith Lords
Pseudo-turn-based d20 system makes twitch irrelevant throughout
Civilization V leans a little harder on reads, though the gap is small.
Civilization V
AI follows scripted personalities, not genuine player modelling
Knights of the Old Republic II: The Sith Lords
Influence system uses scripted dialogue triggers, no adaptive opponent
Civilization V leans a little harder on variance, though the gap is small.
Civilization V
Random starts, barbarian spawns, and goody huts create hidden unknowns
Knights of the Old Republic II: The Sith Lords
Influence thresholds and hidden stat distributions create first-play unknowns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Civilization V
Hex placement, social policies, and victory routing are fully solvable
Knights of the Old Republic II: The Sith Lords
Prestige class chaining and influence-stat transfer create near-broken optimization ceilings
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.
