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
Mastering fixed guard circuits and tool inventories to ghost sprawling levels without a trace.
Shogun: Total War leans Optimization (Pure Optimization); Thief II: The Metal Age 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
Thief II: The Metal Age
Fine arrow placement and rope climbing require care, not twitch
Shogun: Total War leans a little harder on reads, though the gap is small.
Shogun: Total War
Campaign AI daimyos follow mappable behaviors
Thief II: The Metal Age
Mechanist guards run scripted beats, never adapting to tactics
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Shogun: Total War
Fog of war and agent rolls hide information
Thief II: The Metal Age
Camera placements and patrol timing are hidden on first entry
Thief II: The Metal Age leans a little harder on optimization, though the gap is small.
Shogun: Total War
Campaign economy, army composition and terrain are deeply solvable
Thief II: The Metal Age
Loot routing and tool economy are fully optimisable once learned
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.
