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
Sandbox medieval sim spanning personal swordplay up to running a kingdom's economy.

Optimization · Pure Optimization
Engineering silent passages through layered guard awareness systems using body-stacking and sound tools.
Mount & Blade II: Bannerlord leans Optimization (Pure Optimization); Splinter Cell: Chaos Theory 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.
Mount & Blade II: Bannerlord
Directional melee blocking and mounted combat
Splinter Cell: Chaos Theory
Rappel aim, hand-over-hand movement, and knockouts require care
Mount & Blade II: Bannerlord leans a little harder on reads, though the gap is small.
Mount & Blade II: Bannerlord
Multiplayer duels add some human prediction
Splinter Cell: Chaos Theory
Guards talk and investigate on scripted awareness trees
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mount & Blade II: Bannerlord
Procedural campaign politics and battles
Splinter Cell: Chaos Theory
Conversation triggers and item locations hold some first-run uncertainty
Splinter Cell: Chaos Theory leans a little harder on optimization, though the gap is small.
Mount & Blade II: Bannerlord
Economy, army composition, and kingdom management dominate
Splinter Cell: Chaos Theory
Sound-state management and multi-approach routing are the core skill
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.
