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
Solving guard patrols and survival systems through planned stealth routing.

Optimization · Pure Optimization
Sandbox medieval sim spanning personal swordplay up to running a kingdom's economy.
Metal Gear Solid Delta: Snake Eater leans Optimization (Pure Optimization); Mount & Blade II: Bannerlord 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.
Metal Gear Solid Delta: Snake Eater
Stealth movement and CQC need care, not twitch mastery
Mount & Blade II: Bannerlord
Directional melee blocking and mounted combat
Mount & Blade II: Bannerlord leans a little harder on reads, though the gap is small.
Metal Gear Solid Delta: Snake Eater
Guards follow vision-cone scripts, not adaptive minds
Mount & Blade II: Bannerlord
Multiplayer duels add some human prediction
Mount & Blade II: Bannerlord leans a little harder on variance, though the gap is small.
Metal Gear Solid Delta: Snake Eater
Patrol routes unknown only until observed
Mount & Blade II: Bannerlord
Procedural campaign politics and battles
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid Delta: Snake Eater
Camo, routing, food and boss knowledge solve every encounter
Mount & Blade II: Bannerlord
Economy, army composition, and kingdom management dominate
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.
