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
A study-level combat flight sim where mastering each aircraft's real systems is the price of entry.

Optimization · Practiced Mastery
Mastering samurai unit cohesion and clan-specific economic chains across feudal Japan.
DCS World leans Optimization (Practiced Mastery); Total War: Shogun 2 leans Optimization (Practiced Mastery).
DCS World leans a little harder on execution, though the gap is small.
DCS World
Precise stick-and-throttle handling and BFM have a high ceiling.
Total War: Shogun 2
Samurai unit micro, zen arts timing, and castle sieges reward sharp play
DCS World leans a little harder on reads, though the gap is small.
DCS World
Multiplayer dogfights against humans reward genuine prediction.
Total War: Shogun 2
AI daimyo follow scripted clan doctrines; human opponents require reads
Total War: Shogun 2 leans a little harder on variance, though the gap is small.
DCS World
Sensor fog of war and unseen contacts hide information.
Total War: Shogun 2
Metsuke agent skill rolls and random farm yields add moderate unknowns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DCS World
Full-fidelity avionics, weapons and tactics are a vast learnable system.
Total War: Shogun 2
Clan-specific mastery paths and trade port chains are the core solvable layer
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.
