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
A strategy wargame pairing turn-based management of feudal Japan with real-time mass battles.

Optimization · Pure Optimization
A blade-driven JRPG won by chain-attack routing and combo optimization.
Shogun: Total War leans Optimization (Pure Optimization); Xenoblade Chronicles 2 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.
Shogun: Total War
Real-time battle micro matters but pace is forgiving
Xenoblade Chronicles 2
Auto-attack with art-timing inputs
Shogun: Total War leans a little harder on reads, though the gap is small.
Shogun: Total War
Campaign AI daimyos follow mappable behaviors
Xenoblade Chronicles 2
Scripted enemies
Xenoblade Chronicles 2 leans a little harder on variance, though the gap is small.
Shogun: Total War
Fog of war and agent rolls hide information
Xenoblade Chronicles 2
Blade gacha and crit rolls
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Shogun: Total War
Campaign economy, army composition and terrain are deeply solvable
Xenoblade Chronicles 2
Blade combos and chain attack routing central
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.
